Find the rms value of the voltage waveform shown in Figure P5.17.

Q1. Referring to the Figure Q1, answer the following questions: V:(ot) 40 V v(ot) 20 V- Vm1 10 A i(ot) Im Reference( 0°) O = 30 80° i) The maximum and effective (rms) values of v(wt), v1(wt) and i(wt). ii) Write the waveform equations of v(wt), vi(wt) and i(wt). iii) Determine the phase relationship between the voltage, v1(wt) and the current, i(wt) and draw the phasor diagram. iv) Determine the impedance from Q1 (iii).
