<p>This worksheet helps pupils see how adding resistors in series and parallel affects the total resistance of a circuit.<br /> Pupils must use Ohm’s law to calculate resistance using current and potential difference values and then plot a line graph of their results.<br /> 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.</p>

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