How do you calculate the four band resistor?
The fourth band (or 5th for the 5-band and 6-band) indicates the tolerance values. Here, two colors are added (gold and silver). The 6th band for a 6-band type resistor is the temperature coefficient….Resistor Band Colors.
How is color code resistance calculated?
Calculating Resistor Values For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.
What does the four bands indicate in 4 band color code of 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 color is a 330 ohm resistor?
330 Ohm Resistor Color Code: Orange, Orange, Brown, Golden. Resistance: 330 Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 27.52mA .
What is the value of a resistor which has first three color bands are brown black and red?
EXAMPLE: Brown, Black, Red = 1000 Ohms not Black, Brown, Orange as this calculator will display as 1000 Ohms.
Which digit is represented by a blue band on a resistor?
Digit, Multiplier, and Tolerance Band Chart
|Color Name||Digit band||Multiplier band|
What is the color of the 4th band?
The fourth band is black, giving a multiplier value of 100.
