Resistor Equivalent Calculator

The equivalent resistance is the algebraic sum of the resistances (Equation 10.3. 2): RS=R1+R2+R3+R4+R5=20Ω+20Ω+20Ω+20Ω+10Ω=90Ω. The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance: I=VRS=9V90Ω=0.1A.

How do you find the equivalent resistance in a parallel calculator?

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.

How do you calculate resistors?

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. Example: To calculate the total resistance for these three resistors in series.

How do you calculate resistors 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 a equivalent resistor?

The equivalent resistance of a network is that single resistor that could replace the entire network in such a way that for a certain applied voltage V you get the same current I as you were getting for a network.

What is the rule of equivalent resistance?

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

What is the equivalent resistance of resistors in parallel?

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

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 value of equivalent resistance in parallel?

For example, you can easily calculate the equivalent resistance when you have two identical resistors in parallel: it is half of the individual resistance.

What are the 4 types of resistors?

Types Of Resistors

• Thermistors.
• Varistor Resistors.
• Photo Resistor or LDR (Light Dependent Resistors)
• Surface Mount Resistors.

What color is a 470 ohm resistor?

470 Ohm 2W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

What does a 220 ohm resistor look like?

So, the color code of the 220 - ohm resistor is RED - RED - BROWN.

How do you find equivalent resistance in 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.

Is equivalent and total resistance same?

Thus, the equivalent resistance is a different way of indicating the total resistance. It will be calculated differently for series and parallel circuits. The equivalent resistance of any such network will be the single resistor which can replace the entire network with the same effect.

What is the total equivalent resistance?

The voltage drop is the same across each parallel branch. The sum of the current in each individual branch is equal to the current outside the branches. The equivalent or overall resistance of the collection of resistors is given by the equation 1/Req = 1/R1 + 1/R2 + 1/R3

How do you know if a circuit is equivalent?

If both circuits have the same total resistance, then they will be equivalent to each other. The circuit on the right only contains a single resistor, so the total resistance of this circuit is 300 ohms. The circuit on the left contains two resistors connected in series.

What is equivalent rule?

Recall that two propositions are logically equivalent if and only if they entail each other. In other words, equivalent propositions have the same truth value in all possible circumstances: whenever one is true, so is the other; and whenever one is false, so is the other.

How do you find the equivalent resistance of two resistors when connected in parallel?

When resistors are connected across each other in a circuit, they are said to be connected in parallel combination. Consider two resistors, namely R1 and R2, connected in parallel combinations. The total resistance across the voltage is given by 1/R = 1/R1+1/R2.

How do you find the resistance of a parallel circuit with two resistors?

You'll get an equivalent resistance of 1.41 ohms now let's get the same answer using this formula.

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.
