Thanks for your help, uart and tim! :)

Why is it necessary to calculate the impedance? Btw, are all my other steps right?

A resistance 'R' ohm and inductance of 'L' henry are connected across 240V, 50Hz supply. Power distributed in the circuit is 300W, and the voltage across R is 100V. In order to improve the power factor to unity, the capacitor to be connected in series should have a value of __. a) 43.7 uF b)...

Maybe you can use this: M = (f-v)/f 4.125 = 8-v/8 v = 25cm I am not so sure abt the answer. Another formula that you might find useful is M = f/(f+u)
