Electrical capacity of earth is

Calculate the electrical capacitance of earth. The radius of earth is 6400 km.

Why does the electrical conductivity of earth's atmosphere increase with altitude?

Assertion : Electric potential of earth is taken zero. Reason : No electric field exists on earth surface.

Assertion : Electric potential of earth is taken zero. Reason : No electric field exists on earth surface.

Statement-1 : Electric potential of earth is taken to be zero as a reference. Statement-2 : The electric field produced by earth in surrounding space is zero.

STATEMENT-1: When a body is connected to earth, all its charge flows to earth and it becomes electrically neutral. Because STATEMENT-2: Electric potential of earth is zero so the electric potential of body should also become zero.

What happens to the electrical capacitance of a conductor when it is brought closer to an earthed conductor?

The concentric spherical conducting shells are arranged in vacume as shown in fig. the electric capacity of the arrangement between .A. and .B. will be
