Question

Phase Angles: Consider a series circuit in which the capacitive reactance equals the inductive reactance. What is the phase angle between current and voltage for this circuit

Answer 1

X = R, therefore the current and the voltage are in phase, that is, the angles are zero

Step-by-step explanation:

In circuits with capacitors and inductors the phase between current and voltage varies according to frequency , capacitance and induction values, but they go in opposite directions. The first creates a delay in the current and the second an advance.

If it is an RLC type serial circuit, the impedance is

X = √[ R² + (XL- Xc)²

with

XL = wL

Xc = 1 / wc

let's apply this to mention if XL = Xc, the impedance the circuit is resistive

X = R

therefore the current and the voltage are in phase, that is, the angles are zero
