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...

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
