In an experiment to measure the active power drawn by a single-phase RL Load connected to an AC source through a $2 \Omega$ resistor, three voltmeters are connected as shown in the figure below. The voltmeter readings are as follows : $\mathrm{V}_{\text {source }}=200 \mathrm{~V}$, $V_R=9 \mathrm{~V}, V_{\text {Load }}=199 \mathrm{~V}$. Assuming perfect resistors and ideal voltmeters, the Load-active power measured in this experiment, in $W$, is ___________ . GATE EE 2025 Electric Circuits - Three Phase Circuits Question 2 English
