Textbook Question
Chapter 20, Problem 23P
a. An air-core coil is connected to a 200 V, 60 Hz source. The current is found to be 4 A, and a wattmeter reading of 80 W is observed. Find the effective resistance and the inductance of the coil.
b. A brass core is inserted in the coil. The ammeter reads 3 A, and the wattmeter reads 90 W Calculate the effective resistance of the core Explain the increase over the value in part (a).
c. If a solid iron core is inserted in the coil, the current is found to be 2 A, and the wattmeter reads 60 W. Calculate the resistance and inductance of the coil. Compare these values to the values in part (a), and account for the changes.
