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

Answer»

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
