Franklin High School SCIENCE 3421.1.5 Circuit Theory Hand Calculations(Done)

Document Content and Description Below

Activity 1.1.5a Circuit Theory: Hand Calculations Introduction Have you ever used a calculator to add some numbers, looked at the answer, and realized that it was wrong? How did you know that the a ... nswer was incorrect? The calculator gave you an answer; why did you not trust it? You knew the answer was wrong because you understand the fundamentals of mathematics. Your instinct told you that the answer could not be correct. The same is true for circuit analysis. Throughout this course you will be using Circuit Design Software (CDS) to test the circuits that you design. This software will always give an answer, whether it is right or wrong. The only way that you will be able to rely on these answers is if you have an understanding of the laws of circuit analysis. You must develop the same instinct for circuit behavior that you have for mathematics. In this activity you will gain experience applying Ohm’s Law and Kirchhoff’s Voltage and Current Laws to solve simple series and parallel circuits. Equipment  Calculator Procedure 1. For each of the resistors shown below, use Ohm’s Law to calculate the unknown quantity. Be sure to put your answer in proper engineering notation and use the correct units. #1 7.44mA [Show More]
