Question

For which medium capacitance is high ? Air , mica , water , metal ?

Answer 1

Capacitance is the ability of particular a system of electrical conductors and insulators which allows them to store electric charge when a potential difference is present between the conductors. Capacitance can be expressed via a ratio of the electrical charge stored to the voltage across the conductors. Such a condition can only be fulfilled by metals.

Ans) Medium capacitance is high in Metals
