Short Answer

In the series RLC circuit represented by the phasors of FIGURE Q32.7, is the EMF frequency less than, equal to, or greater than the resonance frequency ? Explain.

The EMF frequency is less than resonance frequency

See the step by step solution

Step by Step Solution

Step 1. Given Information

We have been given that EMF phasor lags behind current phasor

Step 2. Solving

Since the EMF phasor lags behind current phasor it means .

As EMF frequency increases decreases and increases and at resonance frequency

Since is greater than we can say that EMF frequency is less than resonance frequency
