The Essay on Electrical Pressure Resistance Current Wire
Electricity has three features that include current, voltage and resistance. Current is the flow of electrons round a circuit that is measured by the ammeter in amps (A). Whilst the voltage, refer to as potential difference, is the driving force that circulates the current around the circuit that acts like an electrical pressure. The unit of measurement for this is Volts (V), which is measured by ...
