Resistance

Resistance resistes the flow of charge - Voltage-Current (V-I) graphs show how the current changes in a circuit as you chnge the voltage.

The current through a component is proportional to the voltrage across it when the resistance remains constant.

Different resistors have different resistances - the steeper the slope the lower the resistance.

Calculating Resistance...

Resistance = Voltage / Current

When electrons move through a resistor, they collide with positive ions. These collisions transfer kinetic…
