Question

Determine the value of V3 in volts where Vs = 15V, V1 = 5V, and V2 = 3V. Put the value of V3 in the box below without the units. For example, if the answer is 1V, enter 1.

Answer 1

Answer:

The value of V₃ is 7 V

enter value =7

Explanation:

Given that,

Source voltage $V_{s}=15 V$

First voltage $V_{1}=5V$

Second voltage $V_{2}=3V$

According to figure,

We need to calculate the value of third voltage

Using Kirchhoff voltage law

$V_{s}+V_{1}+V_{2}+V_{3}=0$

$-15+5+3+V_{3}=0$

$v_{3}=7\ V$

Hence, The value of V₃ is 7.
