Question

relationship b/w workdone and voltage in words?

Answer 1

when an electron is located inside a positive electric field, generated by a positively electrified metal surface, like this:

then on the electron is acting the electric force \(F\), whose magnitude is:
\(F=e\cdot E\)
here \(E\) is the magnitude of the electric field, which is constant for such electric field.
Now the electron, under the action of such electric force \(F\), goes towards the electrified surface, and inside a certain time interval, it travels a distance \(d\), for example

Answer 2

and the work \(W\) done by the electric field \(on\) the electron, is:
\(W=F \cdot d= e \cdot E \cdot d\)
Now the quantity \(E \cdot d\) is the voltage difference \(\Delta V\) between the final position and the initial position of the electron. So, finally, we can write this:
\(W=e \cdot \Delta V\)
