Hi, A complex voltage :
v = 100sin(377t) + 50sin(754t) + 5sin(1508t) V is applied to the LR circuit.
Z1 = 25Ω Z2: R = 13.3Ω Xl = 31.2Ω L = 85.3mH
These I managed to work out:
Determine rms of complex voltage waveform.
i)Obtain an expression for the complex current i
i=2.64sin(377t-1.01c)+0.74sin(754t-1.27c)+0.037sin(1508t-1.264c)
ii) Deduce value of true power that flows in circuit = 79.4V
iii) determine overall power factor. = 0.93
On this part I would like some advise on what to include, even some points and i will go into more detail. (Please find attached schematic and graph)
I remember my teacher mentioning on commenting on the power factor..
iv) Comment on the complex waveforms and the results obtained:
Present and communicate your results and findings in a logical way. Producing appropriate plots to show how the complex voltage and current in the circuit vary with time over one complete cycle will help to communicate your results obtained.
