What are the possible values of resultant resistance?

What are the possible values of resultant resistance?

Solution

  • 1 R = 1 R 1 + 1 R 2.
  • 1 R = 1 2 + 1 6.
  • ⇒ R = 6 4 Ω

How Should 3 resistances of 3 ohm are connected so as to produce a resultant resistance of 1 ohm?

In case the resistances are equal, then effective resistance in parallel is: R/N, where R is the value of resistance and N is the no of resistors in parallel. Now, as per your question, effective resistance is: R=3ohms; N=3 resistors in parallel. Hence, 3ohms/3 resistors in parallel= 1 ohm effective.

What is the maximum and minimum value of effective resistance when two 3 ohm resistors are connected in a circuit?

Maximum and minimum resistance is 9 and 1 ohm respectively. All resistor are of same resistance , R = 3 ohm. We know, equivalent resistance is maximum when all resistance are in series.

When two resistances R₁ and R₂ are connected in parallel their equivalent resistance is?

Explanation: There are two resistors, R₁ and R₂. They are connected parallel which means equivalent resistance will be Rₚ which is equal to 3 Ω. When they are connected in series then equivalent resistance Rₛ is equal to 60 Ω.

What is the effective resistance of the three resistors?

The effective resistance of three resistors connected in parallel is 60/47 Ω. When one wire breaks, the effective resistance becomes 15/8 ohms.

How do you solve effective resistance?

For a circuit with resistances R1 and R2 in series or in parallel as in Figure 2, the effective resistance can be calculated by using the following rules. Rab = R1 + R2. Proof.

What is the effective resistance of the two resistors connected in parallel?

When they are connected in parallel, their effective resistance is 20Ω.

What is the effective resistance between P and Q?

so , ?23 = ?2 + ?3 = 7Ω + 3Ω = 10Ω. Resistors ?4 and ?5 are connected in series, so, ?45 = ?4 + ?5 = 6Ω + 4Ω = 10Ω. ??? = 10Ω /12 = 5/ 6 Ω ≈ 0.83Ω.

What is the effective resistance between points P and Q in the circuit shown in Figure?

electrical circuit shown in the figure is. (a) 2RrR+r. (b)8R(R+r)3R+r.

What is the resistance between P and Q of the following circuit each resistance is of 1 ohm?

⟹Req=78​Ω is the correct answer.

What is the resistance between P and Q of the following circuit each resistance is of 1 ohm and the wire between EB and BD have resistance 0.5 Ohm each?

Each resistance is of 1Ω and the wire between eb and bd have resistance 0.5Ω each. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

Which of the following is equal to 1 ohm?

1 Ohm is defined as the resistance of a conductor with a potential difference of 1 volt applied to the ends through which 1-ampere current flows. Ohms is the SI unit of electrical resistance. Was this answer helpful?

What is the equivalent resistance between any two vertices of a triangle?

Therefore, the equivalent resistance across any two vertices of the equilateral triangle is 4Ohm.

What is the equivalent resistance between any two corners of the triangle?

Answer. So, the equivalent resistance between any two corner is 1.34 ohms.

How do you find the resistance of a triangle?

The triangle of resistors of resistance R0 (1) is rearranged as a series of two resistors in parallel with a third resistor (2). We find the resistance between points A and B to be 2R0/3. We then replace the triangle of resistors with a star of resistors connecting points A, B, and C (3).
