Question

Two parallel plates of a condenser has been connected to a battery of 300V and the charge collected at each plate is 1 microC.The energy supplied by the battery is

Answer 1

Answer:3*10-4

Explanation:energy=VQ/2

Answer 2

Answer:

E = 3 * 10⁻⁴

Explanation:

Two parallel plates of a condenser has been connected to a battery of 300V and the charge collected at each plate is 1 microC.The energy supplied by the battery is

Q = CV

Q = 1 μ C = 1 * 10⁻⁶ C

V = 300 V

=> C = Q/V

=> C = 1 * 10⁻⁶ / 300

E = CV²

=>E =(  1 * 10⁻⁶ / 300 ) * 300²

=> E = 300 * 10⁻⁶

=> E = 3 * 10⁻⁴
