What is electric potential
  • 1 answers

Yogita Ingle 7 years, 4 months ago

In an electrical circuit, electric potential between two points is defined as the amount of work done by an external agent in moving a unit charge from one point to another.
Mathematically,    E = WQ
Where, E = electrical potential difference between two points
W = Work done in moving a change from one point to another
Q = the quantity of charge in coulombs
The potential difference is measured by an instrument called voltmeter. The two terminals of a voltmeter are always connected parallel across the points whose potential is to be measured.
