Batteries are used to store chemical energy. Placing a battery in a circuit allows this chemical energy to generate electricity which can power device like mobile phones, TV remotes and even cars. Generally, batteries only store small amounts of energy. More and more mobile devices like tablets, phones and laptops use rechargeable batteries.
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.
Batteries are stores of chemical energy that can be converted to electrical energy and used as a power source. In this article you can learn about: This resource is suitable for energy and sustainability topics for primary school learners. In this video, learn about different types of batteries and how they work.
Batteries can be used to power portable devices. They let devices use electricity without the need to be plugged into main electricity sources, such as wall sockets. Mobile phones, tablets, the TV remote and torches all use batteries. Some batteries are rechargeable so they can be used again and again.
Batteries are a non-renewable form of energy but when rechargeable batteries store energy from renewable energy sources they can help reduce our use of fossil fuels and cut down carbon dioxide and greenhouse gas production. Find out why batteries may have a key role to play in making our energy supply greener.
Usually a battery is made up of cells. The cell is what converts the chemical energy into electrical energy. A simple cell contains two different metals (electrodes) separated by a liquid or paste called an electrolyte. When the metals are connected by wires an electrical circuit is completed. One metal is more reactive than the other.
