However, in alternating current (AC) the electric current changes direction at 50 times per second (50 Hz or hertz) in the UK supply.Īn example of direct current would be a battery powered torch. For direct current (DC) the electric current flows only in one direction. The labels ‘AC’ and ‘DC’ are used to describe the types of current flow in a circuit. In terms of the hosepipe example, this would refer to the amount of water being released.
The higher the wattage is, the more power and output from the appliance. WattsĪmps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow. Volts are the measurement used to determine how much force is needed to cause the electric current to flow. The more water flowing through the hosepipe, the stronger the current is. You should think of electric current as the flow of water through a hosepipe. Watts / Volts = AmpsĪmps measure the flow of electricity as an electric current. Watts to Amps FormulaĪlternatively to using the calculator, here are some basic equations which allow you to calculate the missing information on your own.
