Question

What does \[\phi\] represent in the voltage and current expressions for a series LCR circuit?

Options

• The angular frequency of the source.

• The peak voltage across the source.

• The time at which resonance occurs.

• The phase angle by which the current lags the voltage.

Answer 1

The phase angle \[\phi\] describes the displacement between voltage and current. In the stated expressions, current lags voltage by that angle.
