QUESTION 1

5 C of charge flows through a wire in 10 s. What is the current in the wire?

QUESTION 2

If a current of 0.8 A flows in a wire, how many electrons pass through the wire in one minute? (Given: The charge on an electron is 1.6 x 10-19 C)

QUESTION 3

An electric current of 200 mA flows through a resistor for 3 seconds, what is the

(a) electric charge

(b) the number of electrons which flow through the resistor?

Given formula: I = Q/t,

  Q = ne where n (no of electrons)
