What is the resistance for a closed circuit - Answers

Find the current due to closing a switch using equivalent resistance and Ohm's law. Practice: Advanced circuit analysis So, our current when our switch is open is going to be equal to the voltage across the resistors, and that's going to be  26 Dec 2019 The equivalent resistance of network when switch is open and closed is. question . A . 9Ω,8Ω. B . 9Ω,7Ω. C . 9Ω,10Ω. D . 4Ω,9Ω. December 26  Answer to (a)What is the equivalent resistance of the circuit when the switch is open and closed?Ropen = ΩRclose = Ω(b) What is (a) What Is The Equivalent Resistance Of The Circuit When The Switch Is Open And Closed?Ropen = ORclose = O(b) What Is The Total Power Delivered To The   17 Feb 2017 To calculate the resistance that is across A and B when the switch is closed, we will need to know the following: The total resistance of a series circuit is equal to 

24/09/2009 · A closed switch directly connects two points in the circuit. It's as though there is a wire between the two points. That is the same as a short circuit between the two points. Although there is a very small (minute) amount of resistance in the wire and switch contacts, for all practical purposes, the resistance of a closed switch and of a short circuit is zero. How to find equivalent resistance when switch is … a) in general, in the open switch, we can ignore the R2 resistor. Thus, the only important resistance is the one on R1. Thus, the open circuit's ER = 66.9 ohms. physics.nmu.edu When switch is open only 65.0 Ω is part of the circuit, so . When the switch is closed then the 65.0 Ω is in parallel with the 96.0 Ω resistor and we find the combined or total resistance as . or . To find the power use the expression . So when the switch is open . When switch is closed we can find power two ways, first use the total

Study 17 Terms | SA Practice Parallel... Flashcards | … The equivalent resistance of a parallel circuit is less than the resistance of any single resistor in the circuit. You have only six resistors available, and all of the resistors have a value of 10.0 Ω. Worksheet: Equivalent Resistance of Resistor … Determine the equivalent resistance of the circuit if switch 𝑆 is closed. Determine the current drawn from the battery if switch 𝑆 is closed. Q4: Basic Electrical Circuit | Component | Pros and Cons ... Open circuit. In the open circuit, electricity flows from one terminal of the electrical source to the other and cannot return to the other terminal. Closed-circuit. A closed-circuit is called a closed circuit, where no part of the circuit is open or disconnected and can transmit electricity through the circuit.

23/01/2012 · This video shows how to find the equivalent resistance in a network consisting of series and parallel resistors.

If you are asking about short circuit and open circuit then “short circuit” is usually equivalent to “closed switch” where as “open circuit” is equivalent to “open switch” So by following that context, * The resistance of a closed switch is consid Finding Equivalent Resistance - YouTube 23/01/2012 · This video shows how to find the equivalent resistance in a network consisting of series and parallel resistors. Equivalent Resistance Question? | Yahoo Answers 10/10/2008 · Equivalent Resistance Question? The drawing shows a circuit that contains a battery, two resistors, and a switch.
