How to find the power of a resistor?
Consider three identical resistors, R. The maximum power each can dissipate is P. Two of the three resistors are connected in series, and the third is connected in parallel with the other two. What is the maximum power this network dissipate?
If voltage V is applied to the network, the power dissipated by the single resistor will be V^2/R. Each resistor of the pair of series connected resistor will have V/2 across it and dissipate (V/2)^2/R. To avoid exceeding the power rating of the single resistor, V must be adjusted so that V^2/R = P. Therefore the power dissipated each of the other two resistors will be P/4 and the total power will be 1.5 X P.
If a balanced three phase AC voltage is applied to the three nodes of the circuit, including the point between the series connected resistors, the voltage can be adjusted so that the maximum power, P is dissipated by each of the three resistors.
