# Nominal value of resistor Calculator

Resistance Tolerance. The fourth band is the tolerance and represents the worst case variation one might expect from the nominal value. The color code for tolerance is as follows: If the nominal value was 34 Ohm and the 4th band of the resistor was gold (5%) the value range would be nominal +/- 5% = 32.3 to 35.7 Standard Resistor Value Calculator: 1%, 5%, 10%. This calculator will select the closest standard resistor value, from 1% 5% or 10% standard EIA values, calculates the error, and prints out a table of the standard values for the given tolerance. The EIA E number is the number of logarithmic steps. For example, for E12 has twelve steps between. So a 1MΩ resistor can vary by 50,000Ω if it has a ppm of 50,000. This means its resistance can be between 950,000Ω and 1,050,000Ω. To use this calculator, a user just enters the component's nominal value and either the tolerance percentage value or ppm value

To calculate the resistance value, you need to group the values of the significant digits bands — i.e., the values of the first two or three bands from the left, depending on the total number of bands. Then you need to multiply that value by the multiplier to get the resistance value of the resistor An example calculating the range of a resistor value is: If the nominal value was 345 Ohm and the 5th band of the resistor was gold (5%) the value range would be nominal +/- 5% = 327.75 to 362.25.

So, when in doubt (and when it's possible) don't hesitate to use a multimeter to double-check the critical components Determining the nominal value depends on how many bands are on the resistor. Resistors with a tighter tolerance have five bands, resistors with higher tolerances have four bands. The first example I give is the looser tolerance resistor with four. The resistor calculator tool calculates the color code for 3band, 4 band, 5 band, and 6 band resistors typically in the range of ohms, Kilo Ohms, and Mega Ohms.

Resistors have a nominal value and a tolerance (the amount of acceptable variation above or below the nominal value). Most resistors have a 1%, 5%, or 10% tolerance and you can find smaller or tighter tolerances. Which values of resistors are available is determined by the tolerance series. For example, in the 5% series, values are selected so. LED Resistor Calculator. To calculate the resistor needed for a simple LED circuit, simply take the voltage drop away from the source voltage then apply Ohm's Law. In other words... where: V S is the source voltage, measured in volts (V), V LED is the voltage drop across the LED, measured in volts (V), I LED is the current through the LED. The value of a resistor is given in ohms and is often referred to as its resistance. Preferred values or e series. For e48 to e192 the values are rounded to 2 trailing digits. Because of this all resistors with a tolerance of 10 overlap. For this task use the resistor value calculator. Calculate the resistor values given by the bands shown below vary from the nominal value due to subtle mechanical and chemical differences that occur during manufacturing. The manufacturer specifies the maximum deviation from the nominal value as a ±percentage. This range of deviation is called the of the resistor family. toleranceTypical tolerance values are ±1%, ±5%, or ±10% To calculate voltage across a resistor in a series circuit, start by adding together all of the resistance values in the circuit. Then, divide the voltage across the circuit by the total resistance to find the current. Once you have the current, calculate voltage for the individual resistors by multiplying the current by the resistance
