P 3.3-7 Determine the value of voltage v in the circuit shown in Figure P 3.3-7.

Do a voltage walk around the circuit, so we can solve for the current in the circuit. Starting at the lower left corner and walking clockwise around the loop we have

Solving for i

SO the voltage v is across the 10 Ω resistor has a voltage drop of

Alternatively, Replace circuit with the following equivalent circuit.

Now use voltage division
