A coil with inductance of 1 H and negligible resistance carries the current shown in the figure below. Determine the maximum voltage that will appear across the coil. (Select the one best answer from the choices given below.) 0 46 (ms) O a. b. 0.5 V e. 50 V f. 100 V g. 250 V h. 500 V i. 1000 V j. 2500 V k. 5000 V

Explanation / Answer

Given data

Inductor value L = 1 H

current vaule 0 A at t=0

1 A at t=2 to 4 ms

0 A at t= 6 ms

voltage acoss inductor V = L di/dt

= 1(1-0/2-0+1-1/4-2+0-1/6-4)

= 1 ( 1/2+0-1/2)

= 0 Volts
