$1.$ All currents by mesh analyses methods and chose one another method $($it will be your own decision$).$ In the first part you have to use given method and use any one another to prove your calculations.$$

$2.$ Calculate power balance of active power and reactive power.

$3.$ Construct vector diagram of currents in complex plane and potential diagram of voltages for outer loop.

$4.$ Determine the voltmeter reading.

$5.$ Determine active power measurement of wattmeter.
