Play generation game with the circuit symbols shown on a PowerPoint. Give pupils 2 minutes to draw and label all of them – allow less time for more able pupils. 4.2.1.2 Electric currents are the flow of charge. Equation for electric current as the rate of flow of charge should be known. For electrical charge to flow through a closed circuit the circuit must include a source of potential difference. Electric current is a flow of electrical charge. The size of the electric current is the rate of flow of electrical charge. Charge flow, current and time are linked by the equation: 1 Define potential difference. State the name of the particle that carries the electrical charge round a circuit. Ask questions such as: What is an electric current? particle moves to cause an electric current? What makes the particle move? Define an electric current. Demonstrate models of electricity and discuss what each part of the model represents and what makes the particles move. Examples could include the rope model, sweets model, water flow model, etc. Model the flow of an electric current using various models and also video clips available on YouTube, eg .
