Students familiar with circuits in physics will also notice that applying Ohm's Law, V = IR, to the power equation results in two more ways to calculate an object's electric power based on the properties of the circuit in which it operates: P=IV=I^2R=\frac{V^2}{R} Resistanc...
How to Calculate Power Factor To calculate power factor, you need apower quality analyzeror power analyzer that measures both working power (kW) and apparent power (kVA). With this data, you can calculate the ratio of kW/kVA. Power Factor Formula The power factor formula can be expressed in...
The magic V I R triangle can be used to calculate all formulations of ohm's law. Use a finger to hide the value to be calculated. The other two values then show how to do the calculation. The symbol I or J = Latin: influare, international ampere, and R = resistance. V = voltage...
