Importance Of Electricity
Electricity can be made in a number of ways. Each method involves the use of a turbine to spin and convert kinetic energy into electricity. The three important ways in creating electricity are sun, wind and water. Water is a source of energy. The flow of water is used to make electricity in a hydroelectric power station. The flowing water can be used to turn turbines and produce small amounts of electricity. The force of water must be very strong. You get electricity in your house through wires, generators, batteries and cells. Sun is another source of energy. The heat from the sun burns fuels that can create electricity. Wind is another cheap ways of creating electricity. When the wind blows, the blades of the windmill begin to spin. The stronger the wind blows, the faster the blades go. This makes electricity.
Without electricity we cannot live. If you take a look at your house, you will see that different devices need electricity in order to work? Electricity is needed for television, computer, air conditioner etc. Electricity from batteries keeps your car running and makes your flashlights shine in the dark. Electricity is made up of atoms. Atoms are made up of three smaller particles. The three main particles are protons, neutron and electron. Electrons spin around the center, or nucleus, of atoms, in the same way the moon spins around the earth. The nucleus is made up of neutrons and protons. Protons form a positive charge and electrons a negative charge. Neutrons do not have a positive or negative charge. Electrons can move from one atom to another in a flow. When these move between atoms, a current of electricity is created. One electron is attached and another electron is lost. Like that electricity passes along a wire and circuit. The charge is passed from one atom to another when electricity is passed. This is how a current of electricity is created.
Nuclear energy is used to create steam to turn turbines. Uranium is split apart to create heat energy. The heat energy is applied to water, creating steam for use in turning a turbine. Once electricity is created, it travels through a transformer and changes from low to high voltage electricity. High voltage electrical current moves within thick transmission lines. Traveling current is kept high above the ground by transmission towers and insulators are employed for the purpose of keeping electricity in the transmission lines. Transmission towers and insulators are vital for ensuring the safe transportation of electricity.
