Electricity Flashcards
1
Q
Electric Field Strength
A
The e.f.s at a point is the force per unit charge exerted on a stationary positive charge at that point.
2
Q
Current
A
Electric current is the rate of flow of electric charge past a point.
3
Q
Potential difference
A
The p.d between two points is the energy per unit charge as charge moves from one point to another.
4
Q
E.m.f
A
The total work done per unit charge when charge flows round a complete circuit.
5
Q
Resistance
A
The ratio of voltage to current
