Kindly solve the below questions:
1. Assume the AC frequency is 50 Hz. Convert these phasors to signals (remember that phasor magnitudes are RMS values of the signals)
(a) V = 115∠90V
(b) I = 10 + 10j A
2. Convert these signals to phasors (remember to us RMS values for the phasor magnitude)
(a) v(t) = 230cos (314t + 20) V
(b) i(t) = 5cos (314t + 10) A
3. Suppose the voltage across a load is v(t) and the current drawn is i(t) where
v(t) = 230cos (314t + 20) V
i(t) = 5cos (314t + 10) A
(a) calculate the complex power, real power, reactive power and apparent power.
(b) calculate the power factor and indicate if it is leading or bagging
