E.M.F Flashcards
1
Q
What does E.M.F stand for
A
Electro motive force
2
Q
Defenition of E.M.F
A
Energy gained per unit charge by charges passing through a supply, when a form of energy is transferred to electrical energy carried out by the charges. Measured in Volts.
3
Q
what is the equation for E.M.F
A
E = J/Q
E = energy transferred or J / Coloumb
4
Q
What is PD
A
PD is measured across a component and its the energy transferred per unit charge by the charges passing through the component. Measured in Volts.
5
Q
Define electrical current
A
flow of electric charge per unit time
