11. AC Circuit Exercises

by M. Bourne


Exercise 1

Given that the current in a given circuit is 3.90 - 6.04j mA and the impedance is 5.16 + 1.14j kΩ, find the magnitude of the voltage.

Exercise 2

A resistor, an inductor and a capacitor are connected in series across an ac voltage source. A voltmeter measures 12.0 V, 15.5 V and 10.5 V respectively, when placed across each element separately. What is the magnitude of the voltage of the source?
