Ellie Hurer and James Stewart explore current, resistance and potential difference. They also discuss the relationship between current and resistance in different components. Suitable for: AQA, ...
The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.
The hindrance to the flow of electric charge is known as Resistance. The obstruction posed in the way of current carrying particles by fixed particles creates resistance in an electric circuit. Since ...
