Capacitors - Engineering

Q1:

A 220  resistor is in series with a 2.2 F capacitor. The time constant is

A 48 s

B 480 s

C 2.42 s

D 24 s

ANS:B - 480 s

Because capacitor has of property of charging and discharging initially it starts charging from 0 hence the circuit has very low and resistance hence that is short circuit I flows through the circuit.
