Two AC sources of equal frequency are in one series loop. The first has a peak value of $21$ V. The second has a peak value of $28$ V and is a quarter of a cycle ahead. What is the peak value of the voltage across both?

← All Quizzes

← Assertion: the average power taken by a pure inductor from an AC source is zero. Reason: the voltage across a pure inductor and the current through it are 90° out of phase.In a phasor diagram the current phasor is drawn 90° behind the voltage phasor, measured against the sense of rotation. Which part is in the circuit? →
