nitially, the switch in the circuit below is closed. If the circuit is still closed what is the current in the resistance? in A, 2 significant figures
Homework Answers
Here if switch is closed for a long time then no current passes through capacitor then entire current passes through the resistor.
Hence current, i =V/R = 5/2 = 2.5 A .
