1. The problem statement, all variables and given/known data The load in Fig. 11.44 draws 10 kVA at PF =0.8 lagging. If |IL |=40 A rms, what must be the value of C to cause the source to operate at PF =0.9 lagging? 2. Relevant equations P(apparent power VA)= |I| |V| cos@ @ = @V - @I cos@= p.f X= Xrms*(2)^0.5 S(complex power)= 0.5 * I * V (cos@ - j sin@) 3. The attempt at a solution I just face a difficulty in knwoing the face of IL I will be thankful if you solved the wole problem.
