Problem: A 3.0 µF capacitor is initially connected to a 9.0 V battery. Once the capacitor is fully charged the battery is removed and a 4.0 ohm resistor is connected between the two terminals of the capacitor.
Part A: Find the current flowing through the resistor 12.0 µsec after the capacitor begins to be discharged.
I want help to find the current flowing through the resistor 12.0 µsec after the capacitor begins to be discharged.
