A voltage is applied across the terminals of an inductor. The voltage is a 2.5 kHz sinusoidal voltage with zero phase angle and a maximum amplitude of 5mV. This voltage is applied across the terminals of the inductor, and the resulting steady-state current has a maximum amplitude of 314.2µA. a) What is the frequency of the current in radians per second? b) What is the phase angle of the current? c) What is the impedance, ZL, of the inductor? d) What is the inductance, L, of the inductor in mH? e) What is the inductive reactance, XL, of the inductor? ww

R 1. Measure the internal resistance of the 1mH inductor. Set up the given circuit with R = 270n and L = 1mH. Apply a sinusoidal voltage as input. Adjust V, = 4Vpp and set the frequency as 20kHz. Observe the input voltage and the V, L voltage across the inductor simultaneously using an ocilloscope and plot both signals. Find the phase difference between these signals and comment on the results.

An inductive coil of resistance 15 ohms and inductance 0.2H is connected in parallel with a 100 micro farad capacitor to a variable frequency supply. Find the frequency at which the total current taken is in phase with the supply voltage. What is this value of this current if the voltage is 200v. Draw a phase diagram
