V = 40 + j35 volts I = 6 + j3 amps The above is the pd across a circuit is given by the complex numbers I am looking to find the phase difference between the phasors for voltage and current. I am also looking to find the power by means od Vx I x cos. Lastly I am looking for a Argand diagram showing relevant phasors. Please provide working or explanation to answer. V 40 j35 53.15041.1850 I 6 j3 6.70826.5650 Current is lags voltage by (41.185-26.565) = 14.620 Power =VI cosθ = 53.150*6.708*cos 14.62 = 344.986, say 345W Argand diagram showing voltage and current are shown below.
