When current flows in the circuit, all the electrons move simultaneously. This then goes through the lightbulb to the positive side of the battery, completing the circuit. Let’s say we have a simple circuit consisting of copper wire, a battery, and a lightbulb.Įlectrons flow from the negative end of the battery through the copper wire. This current is measured in amps, short for amperes, which is an indication of the number of electrons flowing per second. When electrons flow through a circuit, we get an electric current. In this equation, all we do is multiply the kilowatts of a circuit by the time it’s operational to find the kWh. Provided we understand this concept, using a kW to kWh calculator is simple.
KW TO AMP CALC PORTABLE
If we have an array of portable solar panels for home use rated at 2 kW, this means that on a perfectly sunny day, the maximum output of this solar system is 2 kW, though it will regularly produce less than that. We also use watts and kilowatts in solar equations to measure how much electricity the system produces. When we multiply the resulting watts by 1,000, we get kilowatts. Watts are obtained by multiplying voltage and current according to Watt’s Law. When we speak about power, we’re referring to the rate at which appliances consume energy. A kilowatt is a measure of electrical power equivalent to 1,000 W.
