Write a sentence describing how to find the total voltage across a number of cells in series. Add additional cells to the circuit and measure the total potential difference across all the cells. Use the voltmeter to measure the potential difference (voltage) across the bulb. Use the voltmeter to measure the potential difference (voltage) across the battery. We say that they are ‘in series’ with each other. Series circuits:Ī series circuit is one in which all the components come one after the other in a single loop. You are going to take measurements of current and potential difference in series and parallel circuits.Ĭlick on ‘Lab’ to get started. The aim of this activity is to use the Electric Circuits simulation above (by Phet) to investigate the properties of circuits and to discover some circuit ‘rules’ that always apply to circuits. Activity: discover how series and parallel circuits work
