Horsepower to Amperes Calculator

The internet today gives us a wide variety of tools. These include the wide variety of calculators and convertors that are used by nearly all professionals. These calculators make complex conversions and calculations extremely easy, with a few clicks. These web based applications use only a few simple lines of code to achieve the desired results. One of such calculators is the Horsepower to Amperes.
Function
The Horsepower to Amperes calculator calculates the amperes required by an appliance. Horsepower is a unit of power similar to watts. Amperes is a unit of current. Current represents how fast energy moves through a circuit. Power represents the amount of energy output per unit time. Thus we may calculate one quantity from the other if we know the voltage. Voltage measures the total amount of energy in the circuit. We also must account for the efficiency of the circuit and the charge losses in the conductors. Thus we may calculate the current rating of an appliance knowing the power it consumes.

Steps
There are two types of circuits: AC (alternating current) and DC (direct current). Each calculation employs different formulae as well as different quantity and quality considerations. Power is direrctly related to the current and voltage by the following relation
Power = Voltage*Current
Standard AC circuits are 3 phase and here are the steps to calculate horsepower to 3 phase AC current:
1. Multiply the given horse power units by 746. This converts horse power to watts, the international standard unit of power. For example, if you have 50HP, it gives you 37300 watts.
2. Convert the efficiency from percentage to decimal points. For example if the motor is 80% efficient, consider the efficiency to be 0.8.
3. Multiply the given AC voltage by the efficiency, the power factor and the square root of 3.
4. Finally divide the value obtained in the step 1 by the value obtained in the step 3. The value you get is the current requirement of the device.
For DC current:
1. Multiply the given horse power units by 746. This converts horse power to watts, the international standard unit of power. For example, if you have 50HP, it gives you 37300 watts.
2. Multiply the DC voltage by the decimal value of the efficiency.
3. Finally divide the value obtained in the step 1 by the value obtained in the step 2. The value you get is the current requirement of the device.

Applications

Applications of a calculator that converts horsepower to amperes can be found in appliances that use motors. These devices include refrigerators, heat pumps, air conditioners, water pumps, cooling systems, cascade plants. It also has applications in power generation plants small scale electric generators. These calculations are also considered by process industries that use large machinery such as cement blenders. Motors are generally rated by horsepower. It is important to find the no load current of a motor and thereby the appliance. We may find this using the Horsepower to Amperes calculator.
