Question

True or False (#1-11)

The following questions are referring the left figure. When a capacitor is being discharged, the voltage across the capacitor decreases gradually toward zero. When a capacitor is being charged, the voltage across the capacitor suddenly jumps to zero. The value of the maximum voltage across the capacitor (right at the moment when it starts to discharge) is determined by the initial amount of charge and the capacitance. V_c max = the initial charge the capacitance. When the capacitor is fully discharged, the current in the circuit will stay at a stable and constant amount. When the capacitor is fully discharged, the current in the circuit will be zero. In this situation, the battery is disconnected. The current still forms a loop and the capacitor and the resistor are still in series in that loop. The voltage across the capacitor and the voltage across the capacitor are equal and opposite, and add to zero. When the absolute value of the voltage across the capacitor increases, the absolute value of the voltage across the resistor decreases. When the absolute value of the voltage across the capacitor decreases, the absolute value of the voltage across the resistor decreases. At t = 0, at the moment when the switch is thrown at position "b", the current is zero. At t = 0, at the moment when the switch is thrown at position "b", the current is at its maximum value. At t = 0, at the moment when the switch is thrown at position "b", the charge is at the maximum, so is the voltage across the capacitor. After that, both the charge and the voltage will decay exponentially.
