WebDetailed Solution for Test: Inductive & Non-Inductive Circuits - Question 5. In a pure inductive circuit, current is lagging by 90 degrees from the voltage. The power factor is the cosine of the angle in between the voltage and the current. If the angle between the voltage and current is 90, then cos90=0. Hence, the power factor is zero. WebWhen Frequency = 5 µF Suppose a capacitive circuit where: Voltage = V = 3000 V Capacitance = C = 5 µF Frequency = f = 50 Hz To find the capacitive reactance; XC = 1 / 2πfC XC = 1 / (2 x 3.1415 x 50 x 5×10-6) XC = 636.94 Ω Now, current in the capacitive circuit: I = V / XC I = 3000 V / 636.94 Ω I = 4.71 A Related Questions:
