Its the rate of flow of charge

Current= Charge/Time

Charge flow can be positive or negative
-the conventional current direction is taken as the direction of positive charge
-the current is from positive to negative

Current is measured in ammeter and its connected in series with the circuits

Electromotive Force
Electro motif force (EMF) of any electrical source is the work done by the source in driving the unit charge around a complete circuit.

EMF= Work done/Charge
SI unit = Votls

Potential Difference
the potential difference across a component in a circuit is defined as the work done to drive unit charge through the component

Potential Difference= Work done/Charge
SI unit= Joules

Simple Circuits
Consists of
-Cell
has two ends, the positive and the negative. its the power source for the circuit
-Switch
it controls the current in the circuit, it has two stage ( on and off )
-Voltmeter
measures the voltage across the resistance
(its connected parallel in the circuit)
it has two terminals ( positive and negative)
-Ammeter
Measures the current in the circuit
Connected in series with the components
-Wires
used to connect the component in the circuit
