Question

Calculate the no.. of electrons consisting one coulomb of charge

Answer 1

If charge is 1 C, then no.of electrons is 1.6× 10 raise to power -19 C
= 1 divide by 1.6 into 10 raise to power -19 and multiple by 1

= 10 raise to power 19 divide by 1.6

= 10 divide by 1.6 and multiple by 10 raise to power 18

=6.25×10 raise to power 18

Answer 2

Given that

Charge (Q) = 1 C

Electron (e) = 1.6× 10^-19

Number of electron (n) = ?

Q= ne

1 C = n × 1.6×10^-19 C

n = 1/(1.6×10^-19)

n = 6.25 × 10^18 electron
