What does an electric circuit mean? name the device that helps to maintain a potential difference across a conductor in a circuit. when do we say that the potential difference across two pointin 1 volt? calculate the amount of work done to move 2 coulomb of charge fraom pont A to B having potencial +10v and -5v respectively

An electric circuit is a closed loop in which electrons flow.
The device that maintains a Potential Difference in a circuit is the Cell.
We say that potential difference across two points is 1 V if a current of 1A flows across the points and the resistance across the two points is 1 ohm.
Workdone = Q( V¹ - V²)
= 2( 10 - (-5))
= 30 joules
P.S Please confirm the unit!! ;)
