SSC SSC JE Electrical 2025 Mock Test Series (Paper 1 & Paper 2) Electrical and Electronics Measurements
For the circuit shown in the figure, the voltage and current expressions are
v(t) = E1sin(ωt) + E3sin(3ωt) and i(t) = I1sin(ωt - Φ1) + I3sin(3ωt - Φ3) + I5sin(5ωt)
The average power measured by the Wattmeter is
1
\(\frac{1}{2}E_1I_1cos\phi_1\)
2
\(\frac{1}{2}[E_1I_1cos\phi_1+E_1I_3cos\phi_3+E_1I_5]\)
3
\(\frac{1}{2}[E_1I_1cos\phi_1+E_3I_3cos\phi_3]\)
4
\(\frac{1}{2}[E_1I_1cos\phi_1+E_3I_1cos\phi_1]\)
