What is the voltage in the resistor as soon as the switch is closed at t=0.

(a) 0V

(b) Infinity

(c) 220V

(d) Insufficient information provided

I got this question by my school principal while I was bunking the class.

My question is taken from Transients in CR Networks topic in portion Capacitance and Capacitors of Basic Electrical Engineering

Best answer
Right option is (c) 220V

For explanation: As soon as the switch is closed at t=0, there is no charge in the capacitor, hence the voltage across the capacitor is zero and all the 220V voltage is the voltage across the resistor.
