Step 1 :

Observe the diagram :

Now apply source transformation to convert current source to voltage source.

The source current is $\"\"$ .

Resisitor in parallel with the current source is $\"\"$ .

Voltage : $\"\"$ .

The voltage across resistor $\"\"$ is $\"\"$ .

$\"\"$

Redraw the diagram using the source transformation.

$\"\"$

Step 2 :

All the resistance are connected in series.

Equivalent resistance is $\"\"$ .

The total current in the circuit : $\"\"$ .

$\"\"$

The total current in the circuit is $\"\"$ .

Step 3 :

Find the reading in the voltmeter connected across the resistor $\"\"$ .

The voltage of the circuit at the resistor $\"\"$ : $\"\"$ .

$\"\"$

The voltmeter reads a voltage of $\"\"$ .

Solution :

The voltmeter reads a voltage of $\"\"$ .
