Question

To measure voltage,current and power in a single phase circuit with resistive load

Answer 1

$\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}$

With a single-phase, three-wire system (Figure 3 ), the total power is the algebraic sum of the two wattmeter readings. Each wattmeter is connected from one of the hot wires to the neutral, and current is measured in each hot wire. Total Power is calculated as Pt = P1 + P2.
