Let ω = 2π × 60 rad/s corresponding to a frequency of 60 Hz.
(a) Consider v(t) = 100 √2 cos(ωt + 30°) V and i(t) = 10 √2 sin(ωt + 30°) A. Find the corresponding phasors ¯V and ¯I by choosing the rms values for the phasor magnitudes.
(b) Consider the phasors ¯V and ¯I as obtained in part (a), and show how to obtain the time domain functions.
Q. A sample of iron having a volume of 20 cm is subjected to a magnetizing force varying sinusoidally at a frequency of 400 Hz. The area of the hysteresis loop is found to be 80 cm
Evaluate Phase difference between voltage and current: An inductive coil of reactance 15.7 Ω and resistance 32 Ω is connected in series with a capacitor of reactance 79.5 Ω. T
having looked at the circuit, i first wanted to start my frequency from 0 and plot for 10000 to 20000. so in matlab i used f = 0:10000:20000; but the equation for frequency is f= 1
