This worksheet helps pupils see how adding resistors in series and parallel affects the total resistance of a circuit. Pupils must use Ohm’s law to calculate resistance using current and potential difference values and then plot a line graph of their results. This worksheet would make a good homework, activity in a lesson, or would be a good replacement if you don’t have the necessary electrical equipment to do the practical.

This is a complete and ready to go lesson on resistors in series and parallel circuits. The lesson starts with a recap starter on Ohm’s law and IV characteristics. The lesson then guides pupils through writing a method for conducting a practical where they must add resistors in series. A model results table and help with drawing the graph is also given. Similarly pupils are then guided through adding resistors in parallel. The lesson finishes with a traffic light quiz. The summary activity was made up of exam questions from exampro.
