Question

A phasor diagram, consisting of voltage and current phasors of a certain AC circuit, is provided to you. Using this diagram, which of the following can be determined?

$\left(1\right)$ rms value of current and voltage

$\left(2\right)$ phase difference between voltage and current

• A. $\left(1\right)$
• B. $\left(2\right)$
• C. Both options $\left(A\right)$ and $\left(B\right)$
• D. None of these

Answer 1

The correct option is C Both options $\left(A\right)$ and $\left(B\right)$


In a phasor diagram, the peak value of voltage and current is represented by the length of phasors. From this, rms value can be determined.

Phase angle of voltage and current is also shown. From this, phase difference can be calculated.

Hence, option $\left(C\right)$ is the correct answer.
