Q
Q: If a capacitor is charged to a voltage V and then short-circuited, what happens to the charge on the capacitor?
Solution:
Short-circuiting a capacitor allows charge to flow off, resulting in the charge becoming zero.
Steps: 5
Show Steps
Step 1: Understand that a capacitor stores electrical charge when it is charged to a voltage V.
Step 2: Recognize that short-circuiting means connecting the two terminals of the capacitor directly with a wire.
Step 3: When the capacitor is short-circuited, the stored charge has a path to flow out.
Step 4: As the charge flows out, the amount of charge on the capacitor decreases.
Step 5: Eventually, all the charge will flow off, and the charge on the capacitor will become zero.
