Question

Transcribed Image Text:The RC circuit shown in the figure has resistance of R=5kN and the capacitance of C=14µF. The capacitor is initially charged
and at a voltage Vo=20V at t=0, when the switch is closed. How long does it take for the current running in the circuit to go
down to 40% of its initial value? Express your answer in units of ms (milliseconds)using one decimal place.
