![]() ![]() Now that you have the basic terminology covered, it’s time to learn how to convert watts to volts. Whereas volts represent the amount of energy with which electrons pass a specific point within a closed circuit, amps measure the volume of electrons present in the circuit. AmpsĪmperage (or amps) is the unit that measures the flow of electrical current in a circuit. Thus, 1 kilo-volt-ampere is equal to 1,000 volt-ampere. Volts are the unit of measurement of electrical potential flowing through a system.Īnd like watts, volts can also have the prefix kilo- for readings in the thousands. The prefix, kilo-, means 1,000.īecause watts are equal to amps multiplied by, they are also sometimes described as volt-amperes or volt-amps. Therefore, 1,200 watts is equal to 1.2 kilowatts. How do you convert watts to kilowatts ? A thousand watts gives you 1 kilowatt. Watts are used to describe the power used by appliances, whereas kilowatts are usually used to describe the power used in a residential or commercial setting. Watts are the basic unit of electrical power. Let’s run through a brief description of these basic electrical units. This will help you convert watts to volts, convert watts into amps, or convert watts to kVA (kilovolt amps - more about those in a bit). So 10 amps corresponds to a 2200 watt (2.2 KW) device.īecause a home's main service is 240 volts, the math looks like this: 240 volts x 100 amps = 24,000 watts.Before we get to how to convert watts to volts, you need to understand some basic terminology. The current is mostly the power divided by the voltage = P/220 in amps. You cannot specify both current and voltage at the same time. With a better understanding of your RV's electrical system and some simple electrical formulas you can live comfortably on 30 amps with little to no problems. ![]() The key to living on 30 amps is to not exceed the amperage of an individual circuit, and to not exceed a total of 30 amps at any given time. A 50 amp plug has four prongs – two 120 volt hot wires, a neutral wire and a ground wire – that supply two separate 50 amp, 120 volt feeds.Ī 30-amp outlet supplies 3,600 watts (30 amps multiplied by 120 volts). Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.Įquivalent Volts and Amps Measurements for Various Power Ratingsġ2 Volt, you have a 12 Volt power supply that delivers 1 Amp of current.Ī 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements. For example, if you have a power of 10W running at 5V, the current is 10W / 5V = 2A. The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V): The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω): To calculate amps, divide the voltage by the resistance in ohms. Ohm’s Law provides an alternate formula to find volts if amps and the electrical resistance is known. You can calculate Current from Voltage either providing the Power, or Resistance values. ![]()
