Question

When an electron is taken through a potential difference of 16 volt, how much work is done?

Answer 1

Given ,

Charge (q) = 1.6 × 10^(-19) C

Potential difference (v) = 16 volt

We know that ,

The work done to move a unit charge from one point to another point is called potential difference

It is denoted by " v "

Mathematically ,

$\boxed{ \sf{Potential \: difference \: (v) = \frac{w}{q} }}$

Substitute the known values , we get

w = 16 × 1.6 × 10^(-19)

w = 25.6 × 10^(-19) Joule

★ The work done is 25.6 × 10^(-19) Joule
