A 6.0μ F capacitor is charged to 100 V and is then connected across a 500 Ω resistor. (a) What is the initial charge on the capacitor? (b) What is the initial current just after the capacitor is connected across the resistor? (c) What is the time constant of this circuit? (d) How much charge is on the capacitor after 6.0 ms? 7. A 0.12 μ F capacitor is given a charge Q o and is connected across a resistor. After 4.0 s, the charge on the capacitor is Q o /2. What is the resistance of the resistor?...
