What is the 5th band on a resistor?
Resistors with high precision have an extra band to indicate a third significant digit. Therefore, the first three bands indicate the significant digits, the fourth band is the multiplication factor, and the fifth band represents the tolerance.
What is a sense resistor?
Glossary Term: Sense Resistor Definition. A resistor placed in a current path to allow the current to be measured. The voltage across the sense resistor is proportional to the current that is being measured and an amplifier produces a voltage or current that drives the measurement.
What is the value of 6 band resistor?
Example: If the colors on a 6 band resistor is in this order: green, brown, violet, black, gold and orange. The values of color bands will be like this: Green = 5, Brown = 1, Violet = 7, Black = 100, Gold = 5%, Orange = 15ppm.
What is the value of a 5 band resistor?
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 Related Products: Resistors, Resistor Fixed Single-Through Hole
How is the resistance of a resistor determined?
A resistor is identified by its pattern of color of bands. There are 4, 5 and 6 band resistors. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.
How to calculate the sense resistor value Fo Maxim Integrated?
Entering V IN into Equation 2, we get Equation 3 to calculate the sense resistor value. For a 5mA current range example, select range B, which has a maximum current of 20mA, by setting data bits RS2, RS1, and RS0 (0, 1, 0).
Which is the second band of a resistor?
‘a’ represents the 1 st significant digit, which is the first band color of resistor. ‘b’ represents the 2 nd significant digit, which is the second band color of resistor.
