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 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 ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...
