Lesson topic
The topic of this lesson is basic vocabulary used to describe what a device runs on and how it is connected at home. At the B1 level, it is not enough to name an object: you need to be able to specify the power source, the method of connection, and the user’s action.
The words "strøm", "stikkontakt", "ledning", "kontakt", "batteri" and "lader" form a minimal set for describing household appliances. With them, you can say whether the power comes from the mains or from a battery, whether there is a physical connection, and where the problem occurs.
The verbs "å koble til" and "å trekke ut" are needed not as abstract actions, but as standard household commands. The first describes connecting a device to power, the second describes safe disconnection, usually by means of the cord or plug.
In speech, it is important to distinguish between the object and the action. "Strøm" means power or electricity as a resource. "Stikkontakt" is the point in the wall where a device is plugged in. "Ledning" is the cord itself. In this topic, "kontakt" is best understood as a plug or connection contact in a household context; therefore, its use depends on the situation and requires caution.
The lesson phrases show typical patterns: a device runs on mains power — "Det går på strøm"; you need to connect a device — "Jeg må koble den til"; before doing something, you first disconnect the power — "Trekk ut ledningen først"; if the charger does not work, the problem is expressed with "virker ikke". These are practical formulas, not separate grammar topics.
Lesson goal
- The student will be able to name the main elements of household electrical power supply.
- The student will be able to describe how a device is connected and what it runs on.
Examples with explanation
- Det går på strøm. — It runs on electricity.. This is what you say when you need to indicate the power source of a device.. The impersonal "det" is used as a neutral reference to a device or system. The construction "gå på" shows what something runs on.
- Jeg må koble den til. — I need to connect it.. This phrase is needed when the device is not yet connected and will not work without it.. "må" expresses necessity. "den" replaces an item already known from the context, and "til" remains as part of the verbal expression "koble til".
- Trekk ut ledningen først. — Pull out the cord first.. This is a typical instruction before checking, cleaning, or moving a device.. The phrase is built as an imperative sentence. "først" adds the order of actions: first disconnect, then everything else.
- Laderen virker ikke. — The charger does not work.. This is how you express a simple malfunction without specifying the cause.. "virker ikke" is the standard way to say that an object is not functioning. This is more natural than describing the absence of action literally.
- Denne radioen går på batteri, men laderen ligger hjemme, så jeg kan ikke bruke den lenge. — This radio runs on battery power, but the charger is at home, so I cannot use it for long.
New vocabulary: batteri, lader.
Two power sources are contrasted here: autonomous and external. "går på batteri" shows how the device operates, and the second part explains the practical limitation. - Hvis det ikke er strøm, virker verken laderen eller lampen. — If there is no electricity, neither the charger nor the lamp works.
New vocabulary: strøm, lader.
The example shows a causal relationship: the absence of power affects several devices at once. Lexically, what matters here is "strøm" as a condition for operation. - Jeg må koble den til, fordi batteriet er tomt. — I need to connect it because the battery is dead.
New vocabulary: å koble til, batteri.
The phrase is built around a household reason: the device cannot operate autonomously. "den" replaces the already known device so as not to repeat the noun. - Trekk ut ledningen først, hvis du tror at kontakten er løs. — Pull out the cord first if you think the plug is loose.
New vocabulary: å trekke ut, ledning, kontakt.
This is a typical safety instruction. First the action is given, then the condition under which it is especially important. - Det er en stikkontakt bak sofaen, men ledningen er ikke lang nok. — There is a socket behind the sofa, but the cord is not long enough.
New vocabulary: stikkontakt, ledning.
The example shows a natural combination: there is a connection point, but physical connection is impossible because of the cord length. This is a common household situation. - Laderen virker ikke når jeg kobler den til denne stikkontakten, men den fungerer på kjøkkenet. — The charger does not work when I connect it to this socket, but it works in the kitchen.
New vocabulary: lader, å koble til, stikkontakt.
Here the problem is localized not in the device itself, but possibly in a specific socket. The contrast helps describe the malfunction more precisely. - Denne maskinen går på strøm hele tiden, så du kan ikke bruke batteri som alternativ. — This machine runs on mains power all the time, so you cannot use a battery as an alternative.
New vocabulary: strøm, batteri.
The example shows a limit of usage: not all equipment allows both types of power supply. Here, "går på strøm" means constant dependence on the mains. - Kontakten sitter fast, og derfor vil jeg ikke trekke den ut med makt. — The plug is stuck, and therefore I do not want to pull it out by force.
New vocabulary: kontakt, å trekke ut.
The phrase describes a situation where the action is possible, but undesirable. What matters is the natural household context and the cause-and-effect relationship. - Selv om det er strøm i rommet, må jeg koble apparatet til riktig kontakt. — Even though there is electricity in the room, I need to connect the device to the correct contact.
New vocabulary: strøm, å koble til, kontakt.
The presence of electricity alone is not enough: the correct connection is important. The example shows that the vocabulary of this topic describes not only the resource, but also the method of connection. - Når jeg reiser, tar jeg alltid med en ekstra lader, fordi jeg ikke vil stå uten strøm på mobilen. — When I travel, I always take an extra charger with me because I do not want to be left without power on my phone.
New vocabulary: lader, strøm.
This is a more natural B1 situation: the vocabulary is used not in isolation, but in a personal explanation of a habit and its reason.

- ledning — cord, cable. Refers to the cable through which a device is connected to power. Ledningen er for kort. — The cord is too short..
- kontakt — plug; contact, connection. In the topic of electricity, it is used to refer to a connecting element or plug; the meaning depends on the context. Kontakten sitter løst. — The plug is loose..
- batteri — battery. Refers to an autonomous power source when a device is not permanently connected to the mains. Fjernkontrollen går på batteri. — The remote control runs on batteries..
- lader — charger. Refers to a device that supplies power to charge a battery. Jeg finner ikke laderen. — I cannot find the charger..
- å koble til — to connect. Used when a device is connected to a socket, the mains, or another device. Du må koble maskinen til strøm. — You need to connect the machine to electricity..

Study text
Hjemme har jeg flere apparater som går på strøm, men noen går også på batteri. På kjøkkenet står det en maskin som alltid må kobles til en stikkontakt, ellers virker den ikke. I stua bruker jeg ofte en liten lampe med ledning, og noen ganger er ledningen for kort. Da må jeg flytte lampen nærmere veggen. Mobilen går på batteri, så jeg trenger en lader hver kveld. Hvis laderen ikke virker, prøver jeg en annen stikkontakt først. Når noe virker ustabilt, trekker jeg ut kontakten og sjekker alt en gang til. Det er en enkel vane, men den er viktig.
Questions for self-check
- How does the author of the text check the problem if the charger does not work?
- What is the difference in meaning, within the lesson topic, between the words "stikkontakt", "ledning" and "kontakt"?
- How would you explain in Norwegian that a device runs on mains power, but first it needs to be connected correctly?
