A thunder cloud and the earth's surface may be regarded as a pair of charged parallel plates separated by a distance h and the capacitance of the system is c. When a flash of mean current 'I' occurs for a time duration 't' the electric field strenght between the cloud and earth reduced by

One of two parallel conducting plates separated by a distance 2 cm is charged to a potential 1800V, and the outer plate is connected to the earth. What is the magnitude of the electric field intensity in the space between the two plates?

Positive charge q is given to each plate of a parallel plate air capacitor having area of each plate A and seperation between them, d. Then find (i) Capacitance of the system. (ii) Charges appearing on each surface of plates (iii) Electric field between the plates (iv) Potential diffrence between the plates (v) Energy stored between hte plates
