## Voltages & Currents in Resistor Networks

Ohms law calculations and a few basic facts such the Potential Divider rule are really useful tools to work out voltages, currents and resistances in resistor networks, and are essential skills in understanding how circuits work and, when fault finding, understanding why they don´t work! Build your skills by working out some unknown values in the circuits below. Before you try this quiz however, it may be a good idea to look at some the basic facts about currents and voltages in resistor networks and some Ohms Law basics.
