JAMES: Hello and welcome to the BBC Bitesize Physics Podcast. ELLIE: The series designed to help you tackle your GCSE in physics and combined science. JAMES: I'm James Stewart, I'm a climate science expert and TV presenter. ELLIE: And I'm Ellie Hurer, a bioscience PhD researcher. This is episode one of our eight-part series all about electricity.
Using Electricity Electrical Energy. The amount of electrical energy transferred to a device depends on: The time it is used for; The power of the device (the rate at which it transfers energy) Power is the rate of using energy. A 100W light bulb will use more electrical energy than a 60W bulb if they are both on for the same length of time.
Learn about and revise electrical circuits, charge, current, power and resistance with GCSE Bitesize Physics.
Electricity: Static Electricity Electricity: Static Electricity Understanding Static Electricity. Static electricity is the build-up of electric charge on the surface of objects. This build-up of charge is due to the transfer of electrons and can occur when two different materials come into contact and then separate. This is known as frictional ...
Learn about and revise static electricity, electrical charges and electric fields with GCSE Bitesize Physics.
The Van der Graaff generator is a classic demonstration of static electricity. A belt rubs on the inside of a metal sphere, and the friction causes electrons to move onto the sphere. The sphere is supported by a plastic (insulating) stand, and so the electrons build up on the sphere. This means that the sphere builds up a negative charge.

Electricity in generated in power stations using Electromagnetic Induction - When a magnet is moved in a coil of wire, current is induced in the coil. ...
Learn about and revise mains electricity, current and the role of the National Grid with this GCSE Bitesize Physics.
Electric energy = electric power x time (t) And: power = current × voltage. P = VI. Then: Electric energy = VI x t. Electric energy = VI t. This is usually remembered in the form: Electric energy ...
