Physics Magnetic Field Generat. 2120 Homework-9 7. -/6 points My Notes l Knight 33.074 Consider the circuit in Figure P33.74, in which V 3 26 V and R 17 2. The switch has been open for a long time, and it is closed at t 0 s. What is the current through the 17 2 resistor at the following times? 10 n 10 mH Figure P33.74 (a) immediately after the switch is closed (b) after the switch has been closed a long time (c) immediately after the switch is reopened

Explanation / Answer

a)

immediately after switch is closed ,inductor acts as open circuit ,so

I=V/(10+R) =26/(10+17)

I=0.9623 A

I(R)=I=0.9623 A

b)

After long time switch is closed inductor acts as short circuit ,so it acts as simple wire ,so

I(R) =0 A

c)

current before switch is opened

I=26/10 =2.6 A

inductor doesnot allow sudden change ,so

I(R)=2.6 A
