Question

A simple RC circuit consists of a 1-microF capacitor in series with a 2800-Ohm resistor, a 6-V battery, and an open switch. Initially, the capacitor is uncharged. S R 6 V 2800 ? 1 ?F a) What is the time constant of the RC circuit? b) How long after the switch is closed will the current in the circuit drop to 1/3 of the initial value?
