Phasor diagram of load voltage (V), current in pressure coil $\left({\mathit{I}}_{\mathrm{P}}\right)$ and current in current coil $\left({\mathrm{I}}_{\mathrm{C}}\right)$ is shown in the figure when an electrodynamic wattmeter is used to measure power. The reading of the wattmeter will be proportinal to
