Question

Phasor diagrams are primarily used in AC circuit analysis to ______.

पर्याय

• Calculate the resistance of a circuit

• Show the phase relationship between voltage and current

• Determine the frequency of the AC source

• Measure the peak power dissipated in a circuit

Answer 1

Phasor diagrams are primarily used in AC circuit analysis to show the phase relationship between voltage and current.

Explanation:

Phasor diagrams simplify AC circuit analysis by visually representing the phase difference between voltage and current. This is especially useful for circuits containing inductors and capacitors, where voltage and current are not in phase.
