Are you still seeing 2.26 Ω?
Refer to the equation below for clarification: Where:
Regardless, your tools are easy to use and handy. For this example, refer to the figure above with a green, red, blue, and gold band. RapidTables.com |

Which of these the color refers to is dependent on the position of the color band on the resistor. The gold band in this example indicates a tolerance of ±5% which can be represented by the letter J.
In a typical four-band resistor, the first and second bands represent significant figures. 0.01 (resistor value) / 3 (number of resistors) = [parallel resistance value] Ohm's Law Calculators Resistors in parallel, on the other hand, result in an equivalent resistance that is always lower than every individual resistor. Terms of Use |
$$\frac{1}{R_{EQ}} = \frac{1}{R_{1}} + \frac{1}{R_{2}} + \frac{1}{R_{3}} + ... + \frac{1}{R_{N}}$$, When you have only two resistors in parallel: $$R_{EQ} = \frac{R_1\times R_2}{R_1+R_2}$$. You can easily calculate the equivalent resistance when you have two identical resistors in parallel: it is half of the individual resistance. The calculator does not go to 3 spots after the decimal and therefore, shows 0.00 About |
It is also possible to have a 5th band that is the temperature coefficient, which indicates the change in resistance of the component as a function of ambient temperature in terms of ppm/K. This is the correct value. While circuits can be highly complicated, and there are many different ways in which resistors can be arranged in a circuit, resistors in complex circuits can typically be broken down and classified as being connected in series or in parallel. This means that the value 52 MΩ can vary by up to 5% in either direction, so the value of the resistor is 49.4 MΩ - 54.6 MΩ. Know how many resistors you are using (N) This is handy when you need a specific resistance value and don't have an appropriate part readily available. L is the length of the conductor
For example, if you know you need about 500 Ω to get the desired brightness out of an LED circuit, you can use two 1 kΩ resistors in parallel. Create one now.
This multiplier is multiplied by the significant figures determined from the previous bands, in this case 52, resulting in a value of 52,000,000 Ω, or 52 MΩ. Here is the formula for total resistance of resistors of equal value when used in parallel: Note: You can increase the number of resistors for multiple resistance connected in series or parallel. Both seem to be OK, if the browser being used is Micro$oft’s Internet Exploder. Resistors are circuit elements that impart electrical resistance.

Know the value of the resistor (R) Don't have an AAC account? This tool was designed to help you quickly calculate equivalent resistance, whether you have two or ten resistors in parallel. A is the cross-sectional area of the conductor
If you add another resistor in parallel with the first one, you have essentially opened up a new channel through which more current can flow. The third, blue band, is the multiplier. 0.01 / 3 = 0.00333--> The calculator gives 0.56 Ω as the equivalent resistance of a 5 Ω, 10 Ω, 2 Ω, and 1 Ω resistor in parallel.
Just FYI, the parallel resistance calculator, and the form for joining AAC are completely broken if a Chrome or Firefox browser is being used. So there, it's settled. Both conductance and resistance depend on the geometrical dimensions of a wire. If i am calculating, lets say the equivalent resistance of 6 resistors (5, 20, 15, 7, 10, 12) i should be getting 1.56ohms but instead i get 2.26ohms. And I agree you as well with 1.56. mmikerosss, you must have had a finger fault. Power, Voltage, Current & Resistance (P,V,I,R) Calculator This calculator is based on simple Ohm’s Law. The color coding for resistors is an international standard that is defined in IEC 60062. Conductance formula and resistance formula. R is the resistance in Ω, ρ is the resistivity of material in Ω * m, L is the length of wire, A is the cross-sectional area of the wire. For quick calculations on equivalent resistances and many more Download this usefull app on your android device: As we have already shared Ohm’s Law (P,I,V,R) Calculator In which you can also calculate three phase current.
Note: You can increase the number of resistors for multiple resistance connected in series or parallel. In the explanation below, a four-band resistor (the one specifically shown below) will be used.
Enter 2 values to get the other values and press the Calculate button: Enter 2 values of magnitude+phase angle to get the other values and press the Calculate button: The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): The voltage V in volts (V) is eqaul to the current I in amps (A) times the impedance Z in ohms (Ω): V(V) = I(A) × Z(Ω) =
Hello, It would be nice to add a button to confirm the number of resistors in parallel, because if you enter a high value, the page may freeze. Using the table provided below, the green band represents the number 5, and the red band is 2. The total resistance of resistors in parallel is equal to the reciprocal of the sum of the reciprocals of each individual resistor. Only resistors are addressed by this calculator. Doesn’t seem to work below 1ohm ? Resistor Calculator The following are tools to calculate the ohm value and tolerance based on resistor color codes, the total resistance of a group of resistors in parallel or in series, and the resistance of a conductor based on size and conductivity. This is a percentage by which the resistor value can vary. For example, components that are made to military specifications are typically four-band resistors that may have a fifth band that indicates the reliability of the resistor in terms of failure rate percentage per 1000 hours of service. The complex power S in volt-amps (VA) is equal to the voltage V in volts (V) times the current I in amps (A): S(VA) = V(V) × I(A) =
With multiple resistors of the same value this is all you need to do to know the parallel resistance:
