What you practice

These are the CBSE Class 12 Alternating Current skills this quiz is built around.

Convert peak, rms and mean values of sinusoidal sources.
Find reactance, impedance and resonance in series RLC.
Explain power factor and ideal transformer ratios.

A useful tip

At resonance inductive and capacitive reactances cancel, leaving minimum impedance. Current peaks there, so tuning a radio means adjusting toward that cancellation point.
