4 Ohm Resistor Color Code
How do you read a 4 color resistor?
The first two bands represent the digits or significant figures the third band indicates the
What color is a 3 ohm resistor?
3 Ohm Resistor Color Code: Orange, Black, Golden, Golden.
How do you read a 4 digit resistor?
Resistor Code Format Similar to the three digit EIA, the four digit format uses the beginning values to indicate the significant digits while the last digit is the multiplier. 'R' is used to indicate the position of a decimal point. The four digit format allows for higher precision.
What is the current in the 4 ohm resistor?
Hence, the current flowing through the resistor R1 (4 ohms) is 1A.
What is resistor color code chart?
Therefore, the first three bands indicate the significant digits, the fourth band is the multiplication factor, and the fifth band represents the tolerance. For the example shown here: brown (1), yellow (4), violet (7), black (x 100 = x1), green (0.5%) represents a 147 Ω resistor with a 0.5% tolerance.
How do you decode a 4 band resistor?
In the standard four band resistors, the first two bands indicate the two most-significant digits of the resistor's value. The third band is a weight value, which multiplies the two significant digits by a power of ten. The final band indicates the tolerance of the resistor.
How do you calculate resistor color code?
In 6 band color resistor, each band denotes like the following.
- 1st color band is the first significant digit.
- 2nd color band is the second significant digit.
- 3rd Color Band is the third significant digit.
- 4th color band is Multiplier with a power of 10.
- 5th color band is tolerance.
What does the 4th band mean on resistors?
The 4-band resistor color code is the most commonly used resistor. Similar to the 3 band resistor, the first two bands always give the first 2 digits of the resistance value. The third band represents the multiplier while the fourth band represents tolerance.
What color is a 2 ohm resistor?
2 Ohm Resistor Color Code: Red, Black, Golden, Golden. Resistance: 2 Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 354mA .
What color is a 10 ohm resistor?
10 Ohm Resistor Color Code: Brown, Black, Black, Golden. Resistance: 10 Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 158mA .
What color is 1K resistor?
A 1K Ohm resistor can be identified via resistor color codes of Brown-Black-Red-Gold or Brown-Black-Black-Brown-Gold.
What are the 4 types of resistors?
Types Of Resistors
- Thermistors.
- Varistor Resistors.
- Photo Resistor or LDR (Light Dependent Resistors)
- Surface Mount Resistors.
How do you read a color code?
Hex color codes start with a pound sign or hashtag (#) and are followed by six letters and/or numbers. The first two letters/numbers refer to red, the next two refer to green, and the last two refer to blue. ... For example:
- A=10.
- B=11.
- C=12.
- D=13.
- E=14.
- F=15.

What is the meaning of 4 ohm?
A 4-ohm impedance allows car audio speakers to pull more power from a low-voltage car audio amp. Car audio amps are designed for use with low-impedance speakers. So crank it up and enjoy.
What will be the voltage through the 4 Ω resistor?
Voltage across 4Ω resistance =IR=1×4=4V.
What ohm resistor do I need?
We'll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/. 010=860 ohms.
What color is a 24K resistor?
24K Ohm Resistor Color Code: Red, Yellow, Orange, Golden.
What color is a 470 resistor?
470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden. Resistance: 470 Ohm, Power Rating: 1 Watt, Approximate Maximum Current: 46.13mA ..
