How to calculate equivalent resistance

How do you calculate two resistors in parallel? Take their reciprocal values, add the two together and take the reciprocal again. For example, if one resistor is 2 Ω and the other is 4 Ω, then the calculation to find the equivalent resistance is 1 / (1/2 + 1/4) = 1 / (3/4) = 4/3 = 1.33.

What is the equivalent resistance?

Equivalent resistance: If a single resistance can replace the combination of resistances in such a manner that the current in the circuit remains unchanged, then that single resistance is called the equivalent resistance.

How do you find the equivalent resistance of a series circuit?

The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.

What is the formula for the equivalent resistance of two series resistors?

When resistors are connected one after each other this is called connecting in series. This is shown below. To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances. This is done using the following formula: Rtotal = R1 + R2 +R3 and so on.

What is equivalent resistance in parallel?

The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.

How do you find the equivalent resistance of a and B?

3.22) (a), total resistance in the path `ACB`, i.e., `R_1 = 8.5 Omega + 3.5 Omega = 12 Omega` <br> Since `R_1 and R_2` are in parallel, the effective resistance between the points `A and B`, i.e., <br> `R = (R_1 R_2)/(R_1 + R_2) = (3 xx 12)/(3 + 12) Omega = 2.4 Omega` <br> In (Fig.

Why do we find the equivalent resistance?

More resistance means for the less current flowing through the circuit. If the electrical circuit is having many resistances connected, then we need to find their accumulated resistance value. Thus, the equivalent resistance is a different way of indicating the total resistance.

What is the resistance of 2 resistors in parallel?

Two identical resistors in parallel have an equivalent resistance half the value of either resistor.

How do you calculate resistance in a circuit?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

What is the equivalent resistance of three resistors in parallel?

Likewise, if three or more resistors each with the same value are connected in parallel, then the equivalent resistance will be equal to R/n where R is the value of the resistor and n is the number of individual resistances in the combination.

What is the equivalent resistance of the circuit given below?

So the equivalent resistance of circuit is 10Ω.

What will be the equivalent resistance in the following circuit?

Answer: The equivalent resistance is 6 Ω

What is the equivalent of two resistors joined in series?

Two resistors are joined in series, then their equivalent resistance is 90Ω. When the same resistors are joined in parallel, the equivalent resistance is 20Ω.

What is the total resistance if two resistance of 4 ohm and 6 ohm are connected in parallel?

Equivalent resistance Rs=R1+R2+R3=2+4+6=12Ω Was this answer helpful?

When two resistors are connected in parallel then the equivalent resistance is 6 5?

Two resistance wires on joining in parallel the resultant resistance is 6/5 ohms. One of the wire breaks the effective resistance is 2 ohms. The resistance of the broken wire is. Answer: 2 ohm.

How do you find the equivalent resistance between A and B class 12?

Their equivalent resistance will be, RAB=2r3. Q.

What is the equivalent resistance between A and D?

Now all the resistance between the points A to D becomes in series, Hence, we can add all of them and get the final equivalent resistance. Hence, we can conclude that option (C) R=30Ω is the correct answer.

What is the equivalent resistance in Ohm between points A and B?

Hence, The equivalent resistance between points A and B is 85(R)

What is the equivalent resistance of two 10 ohm resistors in parallel?

Hence total resistance will be 5 ohm.

How do you find the equivalent resistance of a Wheatstone bridge?

Since, 2/3 = 4/6, this is the circuit of a balanced Wheatstone bridge. In the balanced state, VB = VD, so no current will flow through the 5 Ω resistance. Now the equivalent resistance of sides AB and BC is R' = 2 + 3 = 5 Ω.
