1Potential Difference
The potential difference between two points is the work done in bringing a charge of +1 C from one point to the other
21 volt
The potential difference between two points is 1 volt if 1 J of work is done in bringing 1 C from one point to the other
3Electric Current
a flow of electric charge
4Potential at a Point
The potential difference between a point and the Earth
5Capacitance
the ratio of the charge to voltage on a conductor
6The farad
A conductor has a capacitance of 1 farad if placing a charge if 1 C on it raises its potential by 1 V
