An introduction into current in a circuit and the way changing the resistance and voltage in a circuit changes the current. There is space to define voltage and resistance, an investigation using resistance wire, space to draw a graph and then an investigation into current around a series circuit. This is all in one 4 page handout. The fifth page has graduated differentiation questions to use with the graph from the resistance wire experiment with walk, jog and run questions to get every pupil stretched to their current level of ability. Suitable for KS3 and ISEB common entrance.
