What is the voltage across a capacitor after 3 time constants if it was charged

What is the voltage across a capacitor after 3 time constants if it was charged to 12 V?

What is the voltage across a capacitor after 3 time constants if it was charged to 12 V?

Step 1: Understand what a capacitor is. A capacitor stores electrical energy.
Step 2: Know that when a capacitor is charged, it reaches a certain voltage. In this case, it is charged to 12 V.
Step 3: Learn about time constants. A time constant is a measure of how quickly a capacitor charges or discharges.
Step 4: Recognize that after 3 time constants, a capacitor is considered to be fully charged.
Step 5: Since the capacitor was charged to 12 V, after 3 time constants, the voltage across the capacitor will still be 12 V.
