1)A 3300 F capacitor is connected in series with a 50 k resistor to a 64 V voltage source. At t=0, the charge on the capacitor is zero. Initially, is almost zero, while is almost 64 V. The current is constant over time. While the voltage across the capacitor changes, the voltage across the resistor remains constant. The voltage across the capacitor is always 64 V. Initially, is almost 64 V, while is almost zero. As the charge on the capacitor increases over time, so does the current through the circuit.2)At what time is the...
