Charging / Discharging circuit
This will focus on Charging and Discharging of RC circuits. The questions will be about these three scenarios.
1. A 6.0 μF capacitor is initially uncharged. It is connected in series with a switch, a 10 kΩ resistor, and an emf (produced by a power supply) of 40 volts. When the switch is closed, the capacitor begins to charge.
2. A capacitor of capacitance C= 2 μF has been charged so that the potential difference between its plates is 100 V. The capacitor is then connected to a 20k Ω resistor, the circuit is closed by closing a switch, and the capacitor begins to discharge.
3. A 50μF capacitor has been charged to a certain potential difference and is then discharged through a resistor. It takes 2ms for the potential difference across the capacitor to decrease to ⅓ of its initial value.
