What exactly are watts, amps, volts, herts and ohms?
Watts is the rate at which electrical energy is used to do something. Watts measure how many joules of energy are used by a device each second. You can relate watts to voltage and current by using Watts = Volts x Amps Amps is the amount of electrical current passing through a point, imagine this as a flow of tiny particles inside a wire, the more of these passing through a point each second mean a greater current. These particles are known as electrons. When you get electrocuted, it is actually the number of amperes flowing through you that kills as more electrons are present to damage your body. For a deeper understanding, electrons have an electrical charge of 1.6 × 10^-19 coulombs, a current of 1 amp has 1 coulomb of charge flowing through each second so thats 6.25 x 10^18 electrons per second! This number is huge and to make our lives easier, we use amperes (amps) to measure current and coulombs to measure charge. Volts is the electrical pressure difference between two points, a hi
