![]() ![]() The appliance power ratings suggested are indicative only. Here’s our guide to the current ratings of commonly-used domestic appliances. It can be cost saving to measure the electric utilization of each appliance by the electric cost calculator. Measure the amperage in your area and then install electrical appliances. ![]() The ampere and the flow of current can be variable in an area. Alternating current (AC) is used to supply things like houses and buildings and mains connected appliances. The same equation is utilised by our amp hours calculator to calculate battery Ah. 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. Our power experts have designed a convenient amperage calculator to help you: Avoid common missteps when determining power requirements Easily calculate. 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. For example, a 20-amp, 120-volt branch circuit has a total capacity of 2,400 watts (20 amps x 120 volts). In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow. Amps Watts/Volts These formulas can be used to calculate the capacity and loads of individual circuits, as well as for the entire electrical service. Instructions: Select the number of phases from the drop-down list Enter the motor rated voltage in volts (V) Enter the motor power rating and select the appropriate unit (HP or kW) Enter the power factor and efficiency of the. Volts are the measurement used to determine how much force is needed to cause the electric current to flow. This motor full-load amperage (FLA) calculator allows you to calculate the full-load current of the AC electric motor. Calculate Current from Power & Voltage (I P / V) Inputs Power Voltage Output Current Calculate Power Dissipated in a Resistor (P I2 R) Inputs Current Resistance Output Power P V XI. 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. If the calculated results haven’t updated after you’ve finished entering your values, click or tap on one of the results.Find out how to convert Amps to Watts here or how to calculate Ohm's Law here. The results are calculated and updated automatically as you enter different numbers or change between the input fields. Select Units: Select your preferred units of measurement for all the parameters This does not apply to a single-layer solenoid coilĬonductor Length: This is used to calculate the resistance of the conductorĬonductor Diameter: This is used to calculate the resistance of the conductor, and provides the scaling factor for comparing against a second coil Number Of Turns: Enter the total number of turnsĬoil Length: Enter the coil length, measured as depicted in the diagram aboveĬoil Diameter: Enter the coil diameter, measured as depicted in the diagram aboveĬoil Depth: Enter the winding depth, as depicted in the diagram. This is used in conjunction with the resistance of the conductor in order to calculate the current You can choose from single-layer solenoid, multi-layer solenoid and flat spiral coil formsĪpplied Voltage: Enter the voltage that will be applied to the coil. This is used to calculate the inductance and the energy stored. then press Calculate to determine the power output required for the amplifier. And do the same for any other product on the market, whatever the brand. A series of audio calculators that sound system designers, engineers. Using the Ampere-Turn Calculator to compare two coilsĬoil Geometry: Select the geometry of your coil from the list.
