ogf induced in a coil is 0.72 V when the current in the coil changes to 1.6 A in 0.25 s. What is the self-inductance L of the coil? An alternating voltage with a peak voltage of 12 V and a frequency 60 Hz is connected in series to a resistor with resistance R : 10 ?, a capacitor with capacitance C-1000 ?F, and an inductor with inductance L 500 mH. Determine the root-mean-square current in the circuit. (a)

Question 4 In Figure Q4, a resistance, R is connected in series with an iron-cored choke coil (r in series with L). The circuit draws a current of 5 A at 240 V, 60 Hz. The voltages across the resistance and the coil are 100 V and 200 V respectively. Analyze the circuit to determine the following (a) the resistance, reactance and impedance of the coil, (b) the power absorbed by the coil, and (c) the power factor (pf) of...
