Students will understand that current is measured in amps using and ammeter and voltage is measured in volts using a voltmeter. They will understand that when a circuit is connected in series:
* voltages add up for components
* currents are the same through all components
When a circuit is connected in parallel:
* voltages are the same across all components
* currents add up for components
You will be able to connect a simple circuit with a power source and globes in series and in parallel, and measure the current and voltage at different points on the circuit. You will complete the measurements of current and voltage that show the differences between series and parallel circuits.
Simulate simple circuits at this BBC interactive site: Circuits and Conductors. and Changing Circuits. Try Learning Circuits at FlashMain. You can find out more information about series and parallel circuits at the Electronics Club. “All About Circuits” explains how voltage, current and resistance relate to each other. Gary Fallidou has produced some excellent videos demonstrating different simple circuits. Choose one video and let me know what you learnt in the comments secion below. You can download Crocodile Clips free for student use at home to learn more about electronic circuits. This site has a whole lot more links to games and activities to help you learm more about simple circuits.
