Question

A 2uF capacitor which is initially uncharged, a 25 K12 resistor, a switch and a 100V battery
are connected in series. When the switch is closed, the initial current in the circuit is
A) 0
B)40Ma
C) 4mA
D) 4A​

Answer 1

Answer: option c

Explanation:

         at t=0 a capacitor acts as a conducting wire

                     so, use V=IR formula directly

                        i.e, 100 = 25 x 10 power 3 x I

                             we get , I= 4mA

      hope u got it mate..................
