How do you calculate the four band resistor?

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.

Color Value
Red 2
Orange 3
Yellow 4
Green 5

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
Green 5 100,000
Blue 6 1,000,000
Violet 7 10,000,000
Gray 8 100,000,000

What is the color of the 4th band?

The fourth band is black, giving a multiplier value of 100.
