The deflecting torque of wattmeter is:
1
\( \propto V_p^2{I_c},\)The deflecting torque of wattmeter is:
2
∝VpIc,, where Vp is the voltage of the moving coil and Ic is the current through the fixed coil
3
\( \propto V_p^2/{I_c},\)where Vp is the voltage of the fixed coil and Ic is the current through the moving coil
4
∝VpIc, where Vp is the voltage of the fixed coil and Ic is the current through the moving coil
