На скільки змінилася протягом 8 с сила струму в обмотці електромагніту з індуктивністю 3,5 мГн, якщо під час цього виникла ЕРС самоіндукції 0,7 В?

Объяснение:

Електрорушійна сила самоіндукції (ЕРС) виникає в котушці під час зміни сили струму. ЕРС можна обчислити за формулою ЕРС = -L * dI/dt, де L - індуктивність котушки, dI - зміна сили струму, dt - час зміни сили струму.

Використовуючи цю формулу, ми можемо обчислити зміну сили струму: dI = -ЕРС * dt / L = -0.7 В * 8 с / 3.5 мГн = -1.6 А.

Таким чином, протягом 8 секунд сила струму в обмотці електромагніту з індуктивністю 3.5 мГн зменшилася на 1.6 А.

VOCABULARY OVERVIEW Choose the correct words to complete the blog. We (1) changed/moved into our new house yesterday. I had really been looking forward to leaving my tiny room in the old semi-(2) detached/ terraced house and filling the new place with loads of new stuff. We're now in the countryside on the edge of a village and my room is right up in the (3) attic / ground floor. Sounds strange but it's amazing. It's really spacious (unlike my last room) and (4) open / airy with a skylight and windows that (5) oversee/overlook open fields. And I have my own (6) drive/staircase to get up there - everyone else is on the (7) storey/floor below! There's plenty of room for my new, big (8) twin/double bed and oak (9) wardrobes / hangings for my clothes. On the floor, I've got two lovely red and green (10) blinds/rugs covering the original (11) floorboards/bricks. The house is old and everything is a bit old-(12) styled / fashioned. The kitchen has an ancient (13) cooker/cook that hasn't seen a saucepan in years and I think the (14) boxes/ cupboards to keep all the plates and things are about a hundred years old. The (15) roof/ ceiling is very low and dad keeps hitting his head when he goes through the doors. I have to say that downstairs the (16) poster/wallpaper is a bit dingy, but we can take it off and redecorate, which will be fun. It's a bit different from being in the (17) blocks / suburbs further from the town centre, in a stylish, modern house with all mod cons. I think it will get a bit cold in winter. There are no radiators-just (18) fireplaces/mantelpieces in every room. But I love it! The (19) community/ neighbours are cool, too. They came round last night with a welcome cake for us all. I'm really glad we've moved here. Mum and dad are (20) hiring / renting the house for three months to see if we like being (21) distant/ away from the town. As far as I'm concerned, we're here to stay and I don't care if there's no public transport - I'll learn to ride a horse!​
