Question

A 5 micro farad capacitor is charged with a battery of 100V. Find the energy stored ​

Answer 1

Answer:

Energy stored = 1/2 × CV^2

E = 1/2 × 5 × 10^(-6 ) × 100 × 100

E = 2.5 × 10^-2 or 0.025 Joule.

Answer 2

Answer:

Energy = 1/2 ( c ) ( v^2 )

            = 1/2 ( 5 x 10^-6 ) ( 100 x 100 )

            = 1/2 (50000 x 10^-6)

            = 1/2 (0.05)

Energy = 0.025 Joules
