Question

I know it is multiple parts, but some of the answers are really short and some are zero.

Please provide explanations with answers.

Thanks so much!

A) The switch has been closed and after waiting a long time it is opened. What is i1 a very long time after the switch is opened?

B) What is i1 a very long time after the switch is closed?

C) The switch has been closed and after waiting a line time it is opened. What is i1 just after this opening?

D) What is i1 just after the switch is closed?

E) What is i2 just after the switch is closed?

F) What is i2 a very long time after the switch is closed?

You aPe toTr u (31p53) The diagram shows an RL circuit with a switch. e =130.0,V,R1 = 10.0 , R2 = 38.0 , R3 = 65.0 and L 4.0 H .RY T-W 8 i2 8 pt The switch has been closed and after uniti has ben coed and nfnl

Explanation / Answer

A)the switch is opened after a very long time then the current I is constant,

the emf across the inductor is zero

B)when switch is closed the inductor acts like an open circuit

then

i2 = 0 i1 = E/R1

Since i2 = 0 V(R2) = 0V

A long time after the switch is closed the inductors acts like a short circuit:

So i1 = V/R1

C) the switch has been closed and after waiting a long time it is opened ,after this opening the current remains same

D) Just after the switch is closed the inductor acts like an open circuit

E)

Just after the switch is closed the inductor acts like an open circuit

then

i2 = 0

F)   Just after the switch is closed the inductor acts like an open circuit

i2=0
