Multiple Choice

Consider the LR circuit shown below. Initially, both switches are open. Switch 1 is closed. a) What is the maximum current in the circuit after a long time? Then, S1 is opened and S2 is closed. b) What is the current in the circuit after 0.05s?

A

(a) i_{max}=0.5 A;

(b) i (0.05s)=1.86×10^{−6} A

(b) i (0.05s)=1.86×10

B

(a) i_{max}=2 A;

(b) i (0.05s)=7.45×10^{−6} A

(b) i (0.05s)=7.45×10

C

(a) i_{max}=0.5 A;

(b) i (0.05s)=0.14 A

(b) i (0.05s)=0.14 A

D

(a) i_{max}=2 A;

(b) i (0.05s)=0.57 A

(b) i (0.05s)=0.57 A

E

(a) i_{max}=0.5 A;

(b) i (0.05s)=0.46 A A

(b) i (0.05s)=0.46 A A

F

(a) i_{max}=2 A;

(b) i (0.05s)=1.8 A

(b) i (0.05s)=1.8 A
