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
