The deflecting torque of wattmeter is:

A. \( \propto V_p^2{I_c},\)The deflecting torque of wattmeter is:
B. ∝VpIc,, where Vp is the voltage of the moving coil and Ic is the current through the fixed coil
C. \( \propto V_p^2/{I_c},\)where Vp is the voltage of the fixed coil and Ic is the current through the moving coil
D. ∝VpIc, where Vp is the voltage of the fixed coil and Ic is the current through the moving coil
Answer» C. \( \propto V_p^2/{I_c},\)where Vp is the voltage of the fixed coil and Ic is the current through the moving coil
