Capacitance of Conductor Numerical for Class-12 Nootan ISC Physics Ch-4
Que-1. A conductor when charged to 1000 V, takes 2 μC of charge. Find the capacity of the conductor.
Ans-1 Q = CV
=> C = Q/V
=> 2 x 10^-6 / 1000
=> 2 x 10^-9 F
=> 2 x 10^-3 x 10^-6 F
=> 2 x 10^-3 μF
Que-2. The capacitance of a spherical conductor is 1 µF. What is its diameter?
Ans-2 Capacitance of spherical capacitor
C = 4πε0R = 4πε0D / 2
where D is the diameter of conductor
∴ D = (1/4πε0) 2C
=> 9 x 10^9 x 2 x 1 x 10^-6
=> 18 x 10^3 m
=> 1.8 x 10^4 m
