However, it’s crucial not to supply any device or system with more than its rated amperage — which also goes for wattage and voltage. Oversupply of electricity can cause permanent damage or fire. High-amperage batteries come in handy when you need to charge or operate devices or appliances ...
Multiple your amperage by your voltage limits. Once you have your power load, subtract all other loads from that to know how much you’ll be left with for lighting. 4. How to Calculate Lux Levels As mentioned above,lux is simply lumens per square foot. Or, the amount of light hitting ...

Calculate the formula. For example, if you have 12 team members, you will have 66 communications channels. To get to the final answer, first subtract 1 from 12, which equals 11. Multiply 12 by 11, which equals 132. Divide by 2, which equals 66 communications channels. Calculate Household ...
Where S is apparent power – sometimes the same as actual power, as in the case of a purely resistive circuit, but usually less – V is the potential difference in volts and I is the current in amperage. Since power, as mentioned, can be equivalently expressed in watts or volt-amperes,...
Electric voltageVvolts AmperageIamps ResistanceRohms V= I × RI = V / RR= V / I Ohm's law.V = I × R, whereVis the potential across a circuit element,Iis the current through it, andRis its resistance. This is not a generally applicable definition of ...
Get the rated voltage and frequency from the motor nameplate. Check that the voltage of the electric supply feeding the motor matches the rated voltage. For the US and Canada, the rated frequency should be 60Hz. If these figures don't match, then measuring the motor current may not give ...
How to Use a Voltmeter. As its name implies, a voltmeter measures voltage. Some models also measure ohms and amperage; these are called multimeters. Meters are available in analog and digital styles. Step 1 Plug the probes into the meter. Red goes to the positive (+) and black to the ...
Phase C amperage (rms) Phase A minus Phase C volts (rms) Phase A minus Phase B volts (rms) Phase B minus Phase C volts (rms) Referring to FIG. 2, a block diagram of the measuring circuit 38 includes three voltage inputs 70 from the three wires 33, 35, 37 and six voltage input...
Find the amperage available from the same generator but at the higher voltage. Divide 3,000 watts by 240 volts. Only 12.5 amperes are available by the same generator at the higher voltage. Take into consideration what you are going to operate with the generator. In other words, the total ...
