Question

if there is a circuit that has a battery and a lightbulb:

will an electron have more electric potential energy on the positive side of the battery or negative side of the battery?

- i think its same because conservation of energy. energy gained by electron on positive side is equal to energy loss electron on negative side. am i correct?


will an electron have more electric potential on the positive side of the battery or negative side of the battery?

- think both sides have same electric potential (same reasoning as previous question). am i correct?

Answer 1

An electron will have more potential energy at the negative terminal. As it goes to the positive terminal that potential energy will be released to do work, increase kinetic energy or produce heat.

Answer 2

thanks
what about potential?

Answer 3

Potential is higher at the positive terminal. It is the place where a POSITIVE charge would have the highest potential energy (compared to the negative terminal)
