In the unlikely event that you don’t know the wattage of an appliance, but you do know the voltage (almost always 240V) and the resistance (ohms), you can calculate the amperage of the device. Ohm’s lawstates: Current (I) = Voltage (V) / Resistance (ohms or Ω) Again, using a...
To find the amperage of a current based on the number of millivolts, you will need to know the number of watts produced by the current. Once you know the number of millivolts and watts, you can use the basic power conversion formula "Watts = Volts x Amps" to find the number of am...
And to do so, you’ll need the following guidelines: Step 1: Using a tape measure, determine the length and width of your space so that you can calculate the surface area. Step 2: From the professional lighting guidelines, check to see which one best fits your office space and type. ...
Amp to Watt conversion: Learn how to calculate watts from volts and amps in both DC and AC circuits. Understand the impact of power factor & reactance on the calculation.
To calculate output voltage from a circuit, use Ohm's law. Voltage is measured in volts, current is measured in amps and the resistance is measured in ohms. The formula needed is V = I x R. You can use this formula in both parallel and series circuits.
Calculate amperage (assuming 120V outlet): Divide average wattage by voltage: 64.38 W / 120 V = 0.54 amps. How much does it cost to power a refrigerator? Did you know that refrigerators typically account for about 7% of a household's total energy consumption? This makes them one of the ...
The wattage of an appliance is determined from its voltage and amperage. You can use the yellow EnergyGuide label on your TV to determine the volts and amps it uses. Using the above example label, here's how you can calculate volts and amps: Translate energy consumption to watt-hours (Wh...
So, if drawing power from a 120-volt outlet, the exact amperage will be 0.43 amps, which is less power than what most appliances use. Here’s how to calculate the amps: Amps = Watts / Volts = 50 watts / 120 volts = 0.43 amps But then again, don’t expect every other 1.6/1.7 cu...
Explain the relationship between amperage, voltage and power. How is torque related to angular momentum? What is the voltage associated with a 1\times 10^{-3} C charge, 2 meters away from it? What does velocity calculate in hydrogeology?
In order to be able to calculate the amperage for our battery, you will be asked to settle on a voltage.Good news! Heaters can be designed to very wide range of voltages. In our example, we’ll specify a 12V battery as a starting point. Remembering that wattage (P) is equal to volt...
