ELECTRICITY

THE POTENTIAL DIFFERENCE

BETWEEN TWO POINTS IS THE WORK

DONE IN MOVING ONE COULOMB OF

CHARGE FROM ONE POINT TO ANOTHER.

RATE OF FLOW OF CHARGE

RESISTANCEPOTENTIAL DIFFERENCE

CURRENT

MEASURE OF HOW MUCH A CONDUCTOR RESISTS THE

FLOW OF ELECTRICITY.

I, A

V=W/QVOLT (V)

R, Ω

Will the bird on the high voltage wire be shocked?

At the end of lesson, student should be able to;-

Describe the relationship between current and potential difference.

State Ohm’s law.Solve problems involving potential difference, current and resistance

THE RELATIONSHIP BETWEEN ELECTRIC CURRENT

& POTENTIAL DIFFERENCE

Potential difference (V) across the ends of a metallic conductor directly

proportional to the current (I) through it, provided that the temperature and

other physical conditions are constant.

What happen to current:-If the voltage increases?If the voltage decreases?

What happen to current:-If the resistance increases?If the resistance decreases?

At the end of lesson, student should be able to;-

Describe the relationship between current and potential difference.

State Ohm’s law.Solve problems involving potential

difference, current and resistance
