The process to find the equivalent resistance in such cases involves: Identifying sections of the circuit that are clearly in series or parallel. Simplifying these sections step by step using the formulas for series and parallel resistances. Repeating the process until the entire circuit is reduced to a single equivalent resistance between A and B.

Find the equivalent resistance between points A and B in the drawing. Always start away from where you are trying to find the resistance between. So we begin by combining the 1 Ω, 2 Ω, and 3 Ω in series. Our circuit becomes. Now we combine 3 Ω and 6 Ω as parallel resistors . Our circuit now looks like

The 3 Ω and the 2.975 Ω are in series so we can replace them with the effective resistance 𝑹 =𝑹 +𝑹 . = . 𝛀+ . 𝛀= . 𝛀 And our last circuit is So we have the 20 Ω resistor in parallel with the 5.975 Ω resistor and so the total resistance between A and B is found from 𝑹

The equivalent resistance of the circuit network across A and B is \[\dfrac{r}{2}\Omega \]. This is the required solution. Note: The resistance of a network is dependent on the type of combination of resistors. From this example, we understand that the resistance can be even lesser than the resistances involved in the circuit.

CONCEPT: Equivalent Resistance: Equivalent Resistance between two Points is the ratio of Potential Difference between them and the amount of current passing through them. Equivalent Resistance can also be defined as the resistance of the resistor which will replace all the resistors between two points and will draw the same current between these two points as it was flowing Earlier.

Explanation: The 1 ohm, 2 ohm and 3 ohm resistors are connected in parallel. Its equivalent resistance is in series with the 4 ohm resistor and the parallel connection of the 5 ohm and 6 ohm resistor. The equivalent resistance of this combination is 80/11 ohm. This is in parallel with 7 ohm to give equivalent resistance between A and B is 3.56 ohm.

Equivalent Resistance Calculation:To find the equivalent resistance between points A and B in a circuit, we need to analyze the circuit and simplify it step by step.Step 1: Identifying Series and Parallel Components- Look for series resistors: Resistors connected in a line with no other components in between.- Look for parallel resistors: Resistors connected at both ends, forming a loop with ...

The combination is used to send current through an external resistance of 2 Ω. Calculate the current through the external resistance. A potentiometer wire has a length of 1.5 m and a resistance of 10 Ω. It is connected in series with the cell of emf 4 Volt and internal resistance 5 Ω. Calculate the potential drop per centimeter of the wire.

Fill a, b, c resistor values >> Click any circuit image ‘Add’ >> Click on Calculate Tip: a, b, c values can be given though below numeric keys ... How to use Fineducalcs Circuit Equivalent Resistance Calculator to find the equivalent resistance. Have the circuit with resistors that can be written in series and parallel combination.

So the equivalent resistance between the points A and B will be $\dfrac{{11R}}{{15}}$. So, none of the options are correct. Note For the resistances which are in series, the current that is flowing through them will be the same. But for the resistances in parallel, the voltage across them will be equal and the current will depend on the value ...

Figure 2 Note: For these types of questions we need to know some basic concepts of electric circuits such as how to find equivalent resistances when connected in parallel or series, how to apply current divider rule in a parallel circuit, and how to apply voltage divider in a series circuit.

Calculate voltages over 3 and 4 Ohm resistors. (= one volt - V1 and one volt - V2) Calculate the currents through 3,4 and 5 Ohm resistors. Get the sum (=I) of the currents. Calculate the total resistance = 1V/I

Thus, the equivalent resistance between a and b of the given network of conductors is $3\Omega $ . Hence, option C is the right answer. Note:In this type of question where the Wheatstone circuit is given, it is important to know if it is balanced or unbalanced.Here, the given circuit is unbalanced, therefore we have first converted the delta connection to star connection.

How to differentiate between resistor series or parallel arrangement. Number of Current flowing paths between two nodes is factor in finding type of block.

Hint: Take the branches in series and solve them and if any two resistance are in series we have to add them and after that they will come in parallel such that when the resistance are parallel we take the reciprocal of all the resistance and add them and finally we got our equivalent circuit. Complete step by step solution: Suppose that the circuit is complete from A and B with a battery and ...

Therefore, the equivalent resistance between A&B in the given circuit is \[\dfrac{{2R}}{3}\] Hence, the option B is correct Note:Students should be careful in solving these types of problems. We should expect a parallel circuit to have more than ...

Therefore, between points A and B, the equivalent resistance is $5050R$. Note: Resistances can also be connected in parallel combination. The inverse of equivalent resistance of parallel combination is the sum of inverse of all resistances. The resistance is the ratio of voltage and current in a circuit by the Ohm’s law.
