A large capacitor of 3000 µF is charged by a constant current. After 1 minute it reaches a voltageof 100 V. At that voltage, the charging circuit is disconnected.a) Calculate the charging current.b) A second identical capacitor is connected across the capacitor, using wires with 1 kΩ resistance. Sketch a graph of the voltages on the two capacitors as a function of time, withappropriate numbers and units marked on the axes.
The potential difference across a charged capacitor is 16 V. The capacitor discharges through a fixed resistor. After a time equal to the time constant, the potential difference has reduced to V. The magnitude of V is:
A capacitor has an initial charge of 10 µC. It is observed
