NOTE

CURRENT ELECTRICITY

CURRENT ELECTRICITY

Electric current is the rate of flow of charge round a circuit. If a quantity of charge Q (coulomb)

flow from the time t (sec) then the electric current, I = Q/t (c/s)

OHM’S LAW

Ohm’s law state that a steady current flowing through a metallic conductor is directly propositional to the potential difference (P.d.) between it ends provided the temperature and other physical conditions are kept constant.

ELECTRICAL COMPONENTS AND THEIR SYMBOL

The following are electrical components and symbol

EVALUATION:   1. State Ohm’s law

1. Draw five electrical component and their symbols

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
