In a series ac circuit, the instantaneous voltage V(t) and current I(t) are given by V(t)=5[cosωt+√3 sin ωt] I(t)=5[sin(ωt+π4)], then
You are given three circuit elements X, Y and Z. When the element X is connected across an a.c. source of a given voltage, the current and the voltage are in the same phase. When the element Y is connected in series with X across the source, voltage is ahead of the current in phase by π/4.But the current is ahead of the voltage in phase by π/4 when Z is connected in series with X across the source. Identify the circuit elements X, Y and Z.When all the three elements are connected in series across the same source, determine the impedance of the circuit.
Draw a plot of the current versus the frequency of applied source and mention the significance of this plot.
An inductance of 200πmH,a capacitance of 10−3πF and a resistance of 10Ω are connected in series with a.c. source 200V,50Hz.The phase angle of the circuit for current and voltage source is:
