Electricity is important in our lives and powers many devices in our homes. If the electricity went out this morning, it would be difficult to function without devices like lights, appliances, and electronics. Electricity comes from power plants and is delivered to homes through wires, where it can power devices plugged into outlets on walls or run on batteries. Electricity can be converted into different forms of energy like heat, light, sound, and motion to power various machines and devices. Proper safety around electricity is important.
