Equivalent resistance formula refers to the resistance of resistors connected in series, parallel or a combination of both. This formula helps us calculate the equivalent resistance easily when two or more two circuit elements are combined together to form complex electrical circuits and the total resistance of the circuit is measured.
Importance of Studying Equivalent Resistance Formula
It is important to study equivalent resistance formulas because it is used to calculate the total equivalent circuit without drawing them physically. It helps us find out the effective value of a resistor that is connected in a series connection or parallel combination if an unknown current flows through a particular branch of a complex electrical circuit.
Ways for Studying Equivalent Resistance Formula
1) Make flashcards-
Flashcards are one of the best ways to study. There is no better way than making your own! Get a piece of paper and label it “equivalent resistance” on one side, 𝑘 𝐿 = R in series + R parallel, then make two columns labeled “R in series”, which will be all terms that follow this formula (the left column), and “R parallel”, where you’ll solve for resistors when they’re in parallel (right column). List out each term separately including units with your first attempt at writing them down. Then go back through and try to simplify or rewrite these equations so they don’t have any variables.
2) Learn the basics-
It is important to understand the basics of equivalent resistance before you try to apply it. This includes understanding Ohm’s law ( V = IR ), series and parallel circuits, and how to solve for resistances in each scenario. Once you have a strong foundation, the concepts of equivalent resistance will be much easier to understand.
3) Practice-
Start practicing applying the equation to circuits! Try solving for resistances in a few simple series and parallel circuit problems. These are great examples of equivalent resistance because you can simply plug your numbers into the formula. If you’re feeling confident, try applying it to slightly harder circuits that have multiple branches or components connected in different ways.
4) It’s important not to be overwhelmed when practicing-
If you find yourself struggling with these equations, just take a step back and review what you know about the basics before moving forward again so these concepts don’t get too difficult all at once. When studying, make sure you understand why each step is happening rather than just memorizing everything without understanding how it works.
5) Gain practical knowledge-
It is important to gain practical knowledge along with the theory. This means working through examples and solving problems as you go. Not only will this help your understanding of the material, but it will also give you the skills you need to apply these concepts.
