Question

A charge of 150 coulomb flows through a wire of electric bulb in one minute. Find

the electric current flowing through it. Write the number of charges that the electron

contains in 1 coulomb.​

Answer 1

I=2.5 , n=93.75×10^19

Explanation:

Given:

Q = 150 C

t = 1 min = 60 sec

I = ?

n = ?

I = Q

---

t

$\: \: \: \: \: = \frac{150}{60} \\ \: \: \: \: \: \: \: = 2.5$

Q = ne

$150 = n \times 1.6 \times {10}^{ - 19} \\ \frac{150 \times {10}^{ 19} }{1.6} = n \\ 93.75 \times {10}^{19} = n$
