engineering recuitment GATE EE 2023-24 Test Series Electrical and Electronics Measurements Measurement of Power Measurement of AC Power
In the measurement of power by 3 voltmeter method connected as shown below. The expression for power consumed in the load is given by
1
\(\frac{{V_2^2 - V_1^2 - V_3^2}}{R}\)
2
\(\frac{{V_2^2 - V_1^2 - V_3^2}}{{2R}}\)
3
\(\frac{{V_3^2 - V_1^2 - V_2^2}}{R}\)
4
\(\frac{{V_3^2 - V_1^2 - V_2^2}}{{2R}}\)
