Question

For the following problem, use the figure below. Determine the value of V3 in volts where Vs = 15V, V1 = 6V, V2 = 9V, and V4 = 4V. Put the value of V3 in the box below without the units. For example, if the answer is 1V, enter 1. 0 / 1 point 34

Answer 1

Given that,

Source voltage = 15 V

Voltage $V_{1}=6\ V$

Voltage $V_{2}=9\ V$

Voltage $V_{4}=4\ V$

According to figure,

We need to calculate the value of V₃

Using Kirchhoff's law

$-V_{s}+V_{1}+V_{3}+V_{4}=0$

Put the value into the formula

$-15+6-V_{3}+4=0$

$V_{3}=15-6-4$

$V_{3}=5\ V$

Hence, the value of V₃ is 5.
