Question

explain why capacitors are of little use for storage of energy for normal domestic purposes of lightingheating and so on.

Answer 1

Answer:

Capacitors are not ideal for energy storage because they discharge very fast and then they are of no use until recharged.

Explanation:

They are designed to perform different tasks than a battery. They are not suitable to deliver slow discharge for a long time like a battery.  

Other than that, they are very expensive and their charging/discharging cycle has a limited lifetime.

Answer 2

Answer:

Capacitors are of little use for storage of energy for domestic purpose because of the following reasons

Explanation:

1.Only limited amount of charge can be deposited on the plates of a capacitor during the charging process, once the charge is utilized the capacitor becomes useless until it gets recharged.

2.When a charged capacitor is connected to a lead, the potential difference across the ends of the capacitor does not remain constant for a long time. As a result, the capacitor discharges quickly.

3.The capacitor is very expensive compared to a battery which is far more efficient for domestic use.
