A 1000 V battery, a 3000 ohm resistor and a 0.5 micro-farad capacitor are connected in series with a switch. The time constant for such a circuit, designated by the Greek letter tau, is defined as the time in seconds that the capacitor takes to charge to 63% of its capacity after the switch is closed. What is the current in the circuit at a time interval 1 tau s (one time constant) after the switch has been closed
