Modelling electrical circuits A great resource from the IOP using a model to explain current, voltage and resistance in series and parallel circuits. This fantastic Phet animation provides a great starting point to begin thinking about charge, conductors, current and energy before electrical circuits are introduced.
Role-playing electrons in a circuit (Activity 5) will help children to see how current flows and that a complete circuit is necessary for a circuit to work. One child could represent a switch to demonstrate how it can be used to break the circuit so that the current stops and the lamp goes out.
Your heart is the pump that drives the blood circulation in the body. It provides the force or pressure for blood to circulate. The blood circulating through the body supplies various organs, like your muscles, brain and digestive system.A battery or generator produces voltage-- the force that drives current through the circuit. Take the simple case of an electric light.
Electrical Circuits This KS2 Science quiz will take you on a tour of electrical circuits, looking at how they work and some of their parts - such as batteries, switches and wires. Electrical circuits are closed paths for currents to flow and they are usually made of components joined by wires.
Homework resources in Series and Parallel Circuits - Physics - Science Military Families The official provider of online tutoring and homework help to the Department of Defense.
Circuits make computers, digital cameras, and video games possible. Circuits are driving an unprecedented rate of change in how we live. In this topic you'll learn about the physics behind the electronic devices we use.
