What is the initial value for the current

Assignment Help Physics
Reference no: EM131059514

Consider an RL circuit with R = 1.6 k?, L = 240 mH and E= 12 V and a switch S. Imagine we put the switch in position a and wait a "long" time. Then we put the switch at position b at t = 0. (i.e., assume that the time is reset to zero at this time.)

a) What is the initial value for the current, just after the switch is put to position b?

 

b) What is the current after a long time passed since the switch is put to position b?

 

c) How long will it take (from t = 0) for the current to drop to one third its initial value?
