Determine 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 equivalent resistance in a parallel circuit?

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 of the two resistors?

The equivalent resistance of two resistors connected in series is the sum of the individual resistances.

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.

How do you find the equivalent resistance of a resistor in series?

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

What is equivalent resistance in series and 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.

What is the equivalent resistance of the series circuit?

For example, when two 6-Ω resistors are connected in series, it would be equivalent to having one 12-Ω resistor in the circuit. This is the concept of equivalent resistance in a series circuit.

How do you find the equivalent circuit?

For a parallel circuit with three resistors, the voltage drop across each resistor equals the supply voltage. In other words, for a parallel circuit, the equivalent resistance is found by adding the reciprocals of the individual resistance values, and then taking the reciprocal of the total.

What is the equivalent resistance of 2 ohm and 3 ohm in series?

The equivalent resistance of two resistance connected in series can be expressed as R=R1+R2. Now from the given information R=2+3=5Ω

How do I calculate resistance?

R = V ÷ I Question What is the resistance of the lamp? To calculate the resistance of an electrical component, an ammeter is used to measure the current and a voltmeter to measure the potential difference. The resistance can then be calculated using Ohm's Law.

What is the equivalent resistance of 2 ohm and 2 ohm in parallel?

The resultant resistance if two 2 Ω resistors are connected in parallel is 1 Ω.

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

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

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 formula for resistance in series and parallel?

"You can find TOTAL RESISTANCE in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 + " Before we get into the calculations, remember what we said at the start of this section: "The total resistance of a parallel circuit is NOT equal to the sum of the resistors (like in a series circuit).

What is the formula of resistance in series?

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 a equivalent formula?

Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.

What is the equivalent resistance of 2ohm 3ohm 5ohm in parallel connection?

Hence, the resistors are connected in parallel and their equivalent resistance is 0.97 ohms.

What is the equivalent resistance of two resistors of resistance 3 and 6 ohms?

∴Equivalent resistance, Reff = 3×63+6 = 189 = 2 Ω. Q. A battery of e.m.f. 15 V and internal resistance 3 Ω is connected to two resistors 3 Ω and 6 Ω connected in parallel.
