Question

1. A 10 Ω resistor, an inductor with a reactance of 20 Ω, and a capacitor with a reactance of 20 Ω are in series across a 200 V sinusoidal source. The circuit is at resonance. What is the voltage across inductor?

2. In a series RC circuit, at what angular frequency will the phase difference be equal to 45 degree?

Answer 1

Answer:

1.As the component we are interested in is an inductor, the reactance of an inductor is therefore called “Inductive Reactance”. In other words, an inductors electrical resistance when used in an AC circuit is called Inductive Reactance.

2.The RC Impedance Triangle

Then: ( Impedance )2 = ( Resistance )2 + ( j Reactance )2 where j represents the 90o phase shift. This means then by using Pythagoras theorem the negative phase angle, θ between the voltage and current is calculated as.
