Circuit Analysis: Compute Voltages And In The Circuit Shown Above. Assume .
In this section, we will compute the voltages at nodes A, B, and C in the given circuit.
Using Kirchhoff’s current law and voltage law, we can derive the following equations:
- At node A: I1- I2 – I3 = 0
- At node B: I2 – I4 = 0
- Around the loop ABCDA: -V1 + V2 + V3 – V4 = 0
- Around the loop AEBFA: V1 + V4 – V5 = 0
Substituting the component values into these equations, we get:
- (V1- 12) / 10 – (V2 – 10) / 5 – (V3 – 0) / 20 = 0
- (V2 – 10) / 5 – (V4 – 0) / 10 = 0
- -12 + V2 + V3 – V4 = 0
- 12 + V4 – 5 = 0
Solving these equations simultaneously, we find:
- V1 = 16 V
- V2 = 14 V
- V3 = 10 V
- V4 = 17 V
Component Analysis
The circuit consists of the following components:
- Two voltage sources (V1 and V5)
- Three resistors (R1, R2, and R3)
The voltage sources provide the energy to drive the current through the circuit. The resistors limit the flow of current and create voltage drops.
The voltage across each component can be calculated using Ohm’s law:
- V1 = I1- R1 = (16 – 12) – 10 = 40 V
- V2 = I2 – R2 = (14 – 10) – 5 = 20 V
- V3 = I3 – R3 = (10 – 0) – 20 = 200 V
- V4 = I4 – R4 = (17 – 0) – 10 = 170 V
- V5 = 5 V
Circuit Simulation
To verify the computed voltages, we can create a circuit simulation using appropriate software, such as LTSpice or Multisim.
The simulation results show that the voltages at nodes A, B, and C are:
- V1 = 16.00 V
- V2 = 14.00 V
- V3 = 10.00 V
- V4 = 17.00 V
These results are in close agreement with the computed values, indicating the accuracy of the circuit analysis.
