Ano ang Imahinasyong guhit na naghahati sa daigdig sa magkaibang araw? Difference between load resistance and Thevenin/Norton resistance? As I said earlier, these are the simplified forms of complex network; containing either single voltage source or single current source (with internal resistance) supplying the load resistor. In the example you've posted, we see two Thévenin circuits that share a 40-ohm load resistor. The element would produce heat as it was designed to do, this is the work the circuit was designed to do (the load). Did Susan Collins explain why she voted against Amy Coney Barrett's nomination? site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Alone both Thévenin and Norton circuits have open-ended terminals. The difference is whether you model the circuit with a Thevenin-voltage-source or a Norton-current-source.

Waveshare AD/DA espansione board setting sampling frequency. In the Norton/Thevenin theorem, what is the definite difference between the load resistance and Thevenin/Norton resistance? Thanks for contributing an answer to Electrical Engineering Stack Exchange! @ChrisM. Actually the reason of calling that resistance as load resistance is the Thevenin's and Norton's equivalent circuits. But the question is what differentiates between the "load" resistor and the "Thévenin" resistor. Did computer games for Commodore 64 really take "25 minutes" to load "if everything went alright"? Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. It can be anything like a resistor, capacitor, inductor, LED or anything. Normally to protect zener diode from heating up we apply a load resistor in series so that a very small voltage appears at the terminals of the zener diode when it is fired. Our 20th year anniversary is May 21, 2020. Gain access to our free AOP (Ask a Professional) Section to get real answers for your questions. Now the question is, if we increase the resistance according to ohm's law V = IR, the current must fall. What's the right way of removing an indoor telephone line? Here I know the load resistance is the 40 ohm resistor. you posted, anyone of 3 resistors can be considered as load resistors while obtaining equivalent Thevenin's or Norton's network, you have to decide through which resistor you want to find current. Impedance and Resistance both oppose the current in circuit, Impedance vs Resistance, Both are almost same,But resistance related to DC Circuit. How long will the footprints on the moon last? Impedance (Z) is similar to Resistance (R) . The original question which you have to tackle is not "Difference between load resistance and Thevenin's resistance" but "Which shall be my load resistor?" Yes... we are 20 years old. For a Norton equivalent, we would see the following circuit: Difference between load resistance and Thevenin/Norton resistance? To question fig. Load resistance is still a resistance, however in the sense of electrical circuits it has a very specific definition; it is the resistance linked between a circuit's output point, and the ground. If you are 13 years old when were you born? So the load resistor, part of or not of the Th/N eq., is determined by where the terminals are placed? If the circuit was more complex, I might not have been able to see it as clear as in this picture, because I don't really know what qualifies 'the load resistor' to differ from the rest of the circuit. It can be anything like a … Why don't libraries smell like bookstores? Why does the US death rate not "match" life expectancy. Resistance load it means there is passive load to impede current flow. All Rights Reserved. Resistance oppose the steady electric current in DC circuit. Is it because of the direct connection to ground? Copyright © 2020 Multiply Media, LLC. Making statements based on opinion; back them up with references or personal experience. These theorems are usually used to find the current through (or voltage across) "LOAD" resistor, obviously Load Resistor is one through which you wish to find current (or across which you wish to find voltage drop). I can also find Thevenin's and Norton's equivalent circuits across other two resistors and I will still be right. Do any of your sources give a circuit schematic example that uses both a Thévenin resistance and a load resistance? But not really why. It's not because of the direct connection to ground but the given terminals \$a\$ and \$b\$. The Overflow #45: What we call CI/CD is actually only CI.

What is difference between resistance and load resistance? A load resistance is simply a resistor which is being used as a load for an electrical network. Unit of Impedance and resistance is ohm and symbol of impedance is Z. Reactance is. What is the relation between load and resistance? Is this photo of a road detouring around a tree authentic? How to increase quality of photos taken through dslr? Use MathJax to format equations. MathJax reference. A load resistance is simply a resistor which is being used as a load for an electrical network. Ano ang mga kasabihan sa sa aking kababata? Is it because of the direct connection to ground? Does freedom of speech mean freedom to mock everything? Generally, the load is the something that is connected to the output of an electrical circuit. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Here I know the load resistance is the 40 ohm resistor. How should I request a professor to restrict communication to email? Does Jerry Seinfeld have Parkinson's disease? What anti-asteroid measures can we take now, or in the near future, if we faced an alien invasion? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Answering by editing origianl question. Ultimately you will have Thevenin's and Norton's equivalent circuits which are nothing but either a voltage source or current source with their internal resistance, connected across the load resistor. What do you call pieces of cardboard with political slogans on them? The Thevenin/Norton resistance is the resistor that comprises the resistance of the Thevenin/Norton. Suppose if you were told to find current through resistor connected to +ve terminal of either battery and node A, you'd have selected that resistor itself as load resistor.
