Electric Circuits Flashcards
1
Q
Define potential difference across the ends of a conductor
A
The energy transferred per unit electric charge flowing through it
2
Q
Define Emf
A
The work done per unit charge by the source (battery)
3
Q
Define terminal potential difference
A
The voltage measured across the terminals of a battery when charges are flowing in a circuit
4
Q
Define current strength
A
The rate of flow of charge
5
Q
Define resistance
A
The ratio of the potential difference across a resistor to the current in the resistor
6
Q
Define the unit of resistance, and what is it equal to?
A
One ohm(Ω) is equal to one volt per ampere
7
Q
What is 1 amp equal to?
A
1 amp is equal to one coulomb per second
8
Q
Define one coulomb
A
The charge transferred in a conductor in one second if the current is one ampere.
