\

(a)

\

Step 1:

\

Find the total impedance.

\

$\"\"$ is in parallel to $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$ is in series with $\"\"$ and $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Step 2:

\

Find the power reading in wattmeter 1.

\

$\"\"$

\

Input voltage is $\"\"$

\

It is in the form of $\"\"$ .

\

Here $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Wattmeter reading is the real part of the power.

\

$\"\"$

\

Solution:

\

Power in wattmeter 1 is $\"\"$

\

\

\

\

(b)

\

From (a): $\"\"$

\

Find the total current in the ciruit.

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

In a series network, current is same through each element.

\

Find the voltage drop across $\"\"$ .
