Circuit Voltage

Question

Answer 1

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 .
