(a) What is the expression for the voltage across a capacitor as it is discharging in a simple RC circuit? (Use the following as necessary: V0 for the initial voltage, R for the resistor, C for the capacitance, and t for the time.) V = (b) What is the ratio of V/V0 at time t = ?? V V0 =
Q1) If a capacitor is capable of discharging a maximum current of 1A to a load, then another equal-capacitance capacitor is connected to the original in parallel, it too being capable of discharging a max. current of 1A, by varying the circuit's resistance & voltage, would it be possible to achieve 2A? Since the two-caps are in parallel increasing the overall capacitance. Please explain
