5 Key points on what is electricity - Worksheet - Year 6

Electricity is a fundamental form of energy observable in positive and negative forms that is vital for powering various devices and technological advancements. It is created by the movement of electrons, which are tiny particles within atoms, and this flow of electrons is commonly referred to as electric current. Electricity can be generated from various sources, including renewable resources like wind and solar, as well as non-renewable sources such as coal and natural gas.

The functionality of electricity is based on the principles of electric circuits, where it flows from a source through conductors and back. The power of electricity can vary depending on the voltage and current; higher voltage and current typically mean more power. Electrical energy can be transformed into other forms of energy such as light, heat, and motion, making it incredibly versatile. The variation in electrical energy is controlled by devices such as resistors and transformers which can alter the voltage and current to suit different applications.
