Question

A flowing of 10⁷ electron per second in a conducting wire constitutes a current of……….A
(a) 1.6 × 10^-12
(b) 1.6 × 10²⁶
(c) 1.6 × 10^-26
(d) 1.6 × 10¹²

Answer 1

(a) 1.6 × 10^-12

Flow of electrons \(\frac{n}{t}\) = 10⁷/sec.

There fore, Current (I) = \(\frac{q}{t}=\frac{ne}{t}=\frac{n}{t}\times e\)

 10⁷ × (1.6 × 10^-19)

= 1.6 × 10^-12 A.
