Practice Questions
Q1
If a capacitor is fully charged and then short-circuited, what happens to the stored energy?
It is released as heat
It is stored in the circuit
It remains in the capacitor
It is lost
Questions & Step-by-Step Solutions
If a capacitor is fully charged and then short-circuited, what happens to the stored energy?
Steps
Concepts
Step 1: Understand that a capacitor stores electrical energy when it is charged.
Step 2: When the capacitor is fully charged, it has a certain amount of energy stored in it.
Step 3: A short circuit means connecting the two terminals of the capacitor directly with a wire, allowing current to flow freely.
Step 4: When the capacitor is short-circuited, the stored energy starts to flow out of the capacitor.
Step 5: As the energy flows out, it creates a current in the circuit.
Step 6: This current generates heat due to the resistance in the circuit.
Step 7: Eventually, all the stored energy is converted into heat and dissipated into the surroundings.
Capacitor Behavior
– Understanding how a capacitor behaves when short-circuited, including the release of stored energy.
Energy Conversion
– Knowledge of how electrical energy stored in a capacitor is converted into heat energy during a short circuit.
