Voltage
Voltage is measure of difference of
electrical force between two points. The volt is
its unit of measure. Voltage is like electrical pressure. If you look at
it like the faucet in your kitchen, when the faucet is fully open, there
is a given amount of flow ( current). If the water
pressure is low, the flow will be small. If you increase the water pressure
but all else remains constant, the flow will increase. It is the same in
an electrical circuit (without the faucet of course). When a given voltage
is applied to a given resistor (a simple electronic device to be covered later) there will be a flow of current. If the voltage
is increased or decreased there will be a corresponding proportionate increase
or decrease in current.
You should remember:
1.Voltage is electrical force.
