What is the electric power formula? Electric power can be given by many formulae. If the work and time are given, then power is calculated by dividing them. If the current and voltage are given, then power is calculated by multiplying them. Finally, if the resistance and current are given...
Note 1: according to thecurrent calculation of "power double", and the current of the motornameplate on some of the larger error, general kilowatts, calculated thecurrent ratio on the nameplate slightly larger, while the number of kW smaller,the calculated current is smaller than on the name...

However, If the problem is given like , "you have a 100W with resistance 0,32 ohm what's the current? that'd come up as I=Sqroot(P/R)=17,6A First result doesn't make sense, or doesn't look "realistic" but the second one does. But they both stem from the same formula: P...

It cannot be sold; though, it does waste power in the resistance of electric lines between load and generator. The parallel capacitor corrects this problem. Note that the reduction of line losses applies to the lines from the generator to the point where the power factor correction capacitor is...
In a parallel circuit, the individual resistances are calculated using the formula 1/R = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn, where R is the total resistance and R1, R2, R3, etc. are the individual resistances. This means that you need to find the reciprocal of each...
