CURRENT ELECTRICITY
➢ This is the flow of electrons through a conductor per unit time.
A push called voltage is needed to enable the charges to flow. The charge move from high potential
energy to low potential energy.
o SI-Unit of current is ampere (A).
Ammeter
➢ This is a device used to measure current.
POTENTIAL DIFFERENT (P.D) AND ELECTROMOTIVE FORCE
POTENTIAL DIFFERENT (P.D)
➢ This is the electrical pressure in a closed circuit
OR
➢ This is the work done per unit charge in a moving electric current from one point to another.
