Question

A. What is the conventional direction of flow of current? How does it differ from actual direction of electric current?
B. A flash of lightning carries 10C of charge which flows for 0.01s. What is the current?​

Answer 1

Answer:

(A) Conventional direction of current is taken to be from the positive terminal to the negative terminal. It is different from the actual direction of current, as electrons, that carry current flow from the negative terminal to the positive terminal.

(B) we know,

Current = Q/t

here, Q = 10 c

and, t = 0.01s

Current = 10/0.01 = 10/(1/100) = 10 × 100 = 1000 Ampere
