Question

Calculate the number of electron in one micro coulomb of

negative charge

a) 6.25x 1018 electrons b) 6.25 x10-18 electrons

c) 6.25 x 1012 electrons d) 6.25 x 10-12 electrons​

Answer 1

Answer:

c. 6.25×10¹²

Explanation:

charge = No. of electrons × charge of electron

$q \: = n \: e$

$n \: = \frac{q}{e}$

$n \: = \frac{1 \times {10}^{ - 6} }{1.67 \times {10}^{ - 19} }$

$n \: = 6.25 \times {10}^{12}$
