we know power (p) = v^2/R and p = I^2R. if it is asked to find resistance how do we know which formula to use. please explain in detail

Solution

We can find the Resistance using the formulae
P = V^2 / R
R = V^2/ P , if Voltage and Power are given

We can use the formulae P= I^2 x R
R= P/ I^2

if Power and Current are given

A motor that pumps up water to a tank requires 10kW power. Its operating voltage is 220V. The only available resistor has a resistance of 11Ω. We know that we must use n such resistors in series and p such series resistor combinations in parallel. The values of n and p are respectively
