Q: In a circuit, if a capacitor is fully charged, what is the voltage across it?
Solution:
When a capacitor is fully charged, the voltage across it is equal to the voltage of the source it was connected to.
Steps: 5
Show Steps
Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
Step 2: Know that a capacitor can be charged by connecting it to a voltage source, like a battery.
Step 3: When the capacitor is connected to the voltage source, it starts to store energy and builds up a charge.
Step 4: A fully charged capacitor means it has stored as much energy as it can from the voltage source.
Step 5: The voltage across the fully charged capacitor is the same as the voltage of the source it was connected to.
