Question

The current flowing through the inductance coil of resistance 173 ohm which is connected to 50 hz a.C. Is found to lag the supply voltage by an angle of 30o. The inductance of the coil is

Answer 1

Answer:

Given: Resistance = 100 Ohm Frequency(f) = 1000 Hz Phase Angle = 45° Z ... What is the inductance of the coil? audEfLh ... What is the line current and the total power absorbed?

Answer 2

Explanation:

Then, the peak current is calculated by the voltage divided by the resistance. The resonant frequency is found from Equation 15.5.5: f0=12π√1LC=12π√1(3.00×10−3H)(8.00×10−4F)=1.03×102Hz. At resonance, the impedance of the circuit is purely resistive, and the current amplitude is I0=0.100V4.00Ω=2.50×10−2A.
