एक संतुलित, डेल्टा-कनेक्टेड, 3-फेज, विशुद्ध रूप से प्रतिरोधी (purely resistive) लोड पर 220 V का 3-फेज वोल्टेज लगाया जाता है। रिएक्टिव पावर का एक्टिव पावर से अनुपात ज्ञात कीजिए।

In an AC parallel circuit consisting of multiple branches, the total admittance (Y) is the phasor sum of the individual branch admittances. Which of the following expressions correctly represents the magnitude of the total admittance in terms of total conductance (G) and net susceptance (B)?

What happens to the phase angle between the voltage and the current in a series resistor-inductor (R-L) circuit when the frequency of the applied AC voltage is increased?
