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
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.
