kitchen stoves and automobiles are all electrical products — and that's without even thinking of the Internet, computers and cellphones. Electrical circuits are particularly practical because they work accordin
Voltage is used when referring to electricity. Devices that require electricity have a written note that indicates the voltage required and whether it's direct current (DC) or alternate current (AC). Most of the times, devices come with adapters that allow you to plug a 12 volt machine in ...
To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm's Law isE=I⋅R, which tells us to then multiply I by R . E is the voltage across the component also known as voltage drop. How is design current calcul...
To find kWh, multiply Ah by voltage and divide by 1,000. For a 100Ah battery at 12V, the calculation is: 100Ah×12V÷1000 = 1.2kWh If the battery is 100Ah at 24V, it stores 2.4 kWh of energy. The total energy depends on voltage. How long will a 100Ah battery run a fridge? A...
If you multiply the volts by the amps, you get the wattage. In this case, 120 volts multiplied by 10 amps equals 1,200 watts. This holds true for any electrical appliance. If you plug in a light and it draws half an amp, it's a 60-watt light bulb. Let's say that you turn ...
It is important to understand the precision required by the application. This will help identify critical specifications. With the requirement in mind, multiply temperature drift by the specified temperature range. Add initial accuracy error, thermal hysteresis, and long term drift over the intended pr...
have a 1.5 volt reference with a 10 bit ADC. So divide 1.5 by 1024 that gives you .00146484375. So the take the result returned by the ADC and multiply that by .00146484375. Then multiply that result by 2 (because the input to the ADC is ...

Turn off power to the GFI outlet. Test for absence of power with a voltage tester. Place one probe in each slot above the GFI and then below to verify that no power is present. Step 2 Remove the GFI cover plate screws with a flat-head screwdriver. Set the cover plate aside. ...
1: Figure out how many equipments need to be protected; 2: List the amps and volts for each piece of equipment, multiply the voltage and the amperage to get the VA rating. (If your devices' power consumption is stated in Watts (W), please divide the watts by power factor. For servers...
