Question

Doubt 1... I ll post it wait!

Answer 1

I had a huge discussion...

i say the current remains 5 itself :P

but the given answer is MORE than 5 :-/

Answer 2

woah revolution

Answer 3

@Vincent-Lyon.Fr

Answer 4

0.5 i meant :-/

Answer 5

You are right.
The current in a series circuit containing an inductance is always a continuous function.

Answer 6

so i was arguing with 10 teachers with 15 to 20 years experience Each!!!

no one was ready to belive me :'(


i said. AT THAT instant.. the current MUST BE same
and a little LATER in time.. the current would DECREASE


but they all said. we should consider a little later in time, and they said.. the induced EMF INCreases the current momentarily!!!

this is what i tried to explain

that if at t= 0, the resistance is changed, then current slowly would DECREASE and not surely increase


so everything i said is correct? @Vincent-Lyon.Fr
