Circuit Theory B
Description
As much fun as it is to analyze circuits by hand, the process becomes tedious as circuits grow in size and complexity. This is where Circuit Design Software (CDS) comes to the rescue. As the name implies, the CDS is a software tool that can be used to enter and simulate analog and digital circuit designs. As with most computer applications, the CDS handles the mundane and repetitive tasks associated with analyzing circuits, allowing the designer (you) to concentrate on producing quality and creative designs. In this activity you will gain experience using the Circuit Design Software to analyze simple analog circuits. In future activities we will use the CDS to analyze digital circuits as well. The circuits analyzed are some of the same circuits that were analyzed by hand in Activity 1.2.2. Thus, the theoretical and simulation results can be compared.
Conclusion Questions
1. Being able to calculate circuits by hand still remains helpful because if a computer or other technology is not available, all thats left is mental math. Also, the CDS program is a software that has to be purchased. If money is short, its very useful to be able to perform these by hand.
2. Kirchhoff's Voltage Law says Vr1+Vr2+Vr3=Vt. This means that the voltage from each resistor adds up to the total amount of voltage given. In question three, the given voltage was 9. Each resistor was as follows: R1 - 2.18 v / R2 - 5.57 v / R3 - 1.25 v. If all these values are added together, it equals to 9.
3. Kirchhoff's Voltage Law says Vr1+Vr2+Vr3=Vt. This means that the voltage from each resistor adds up to the total amount of voltage given. In question five, the given voltage was 12. Each resistor was as follows: R1 - 1.46 mA / R2 - 1.77 mA / R3 - 2.55 mA. If all these values are added together, it equals 12.
