Question

Select the THREE ways that the parallel-plate capacitor differs from a car battery.

1. battery is capable of continuous current, capacitor is not

2. battery maintains a potential, capacitor does not

3. battery stores chemical energy, capacitor stores electric energy

4. capacitor stores chemical energy, battery stores electric energy

Answer 1

battery stores chemical energy, capacitor stores electric energy

battery maintains a potential, capacitor does not

battery is capable of continuous current, capacitor is not

Step-by-step explanation:

Answer 2

1. battery is capable of continuous current, capacitor is not

2. battery maintains a potential, capacitor does not

3. battery stores chemical energy, capacitor stores electric energy

Step-by-step explanation:

1. battery is capable of continuous current, capacitor is not

This is because the battery maintains a constant current throughout while the capacitor maintains an exponential decaying current.

2. battery maintains a potential, capacitor does not

This is because, the battery has a potential at its terminal due to its emf whereas, the capacitor needs a potential to be applied to its terminals.

3. battery stores chemical energy, capacitor stores electric energy

This is because, the battery converts chemical energy to electrical energy whereas, the capacitor stores electric energy due to its ability to store electric charge.
