• Current Electricity

Capacitance (in F) of a spherical conductor with radius 1 m is

1. 10^-3
2. 1.1 X 10^-10
3. 9 X 10^-9
4. 10^-6

Answer

Capacitance of a spherical conductor is given by

C = 4πε_or

where r = radius of spherical conductor

C = 4πε_o = 1/(9x10⁹) = 1.1 x 10^-10 F

The correct option is B.
