What size resistor is for amp turn on pop sounds 1k resistor color code
The purpose of a 1k resistor in an amplifier circuit is typically to reduce or eliminate “turn-on pop” sounds that can occur when the amplifier is powered on or off. The resistor helps to discharge any DC voltage that may be present in the input or output resistor color code capacitors of the amplifier, which can otherwise create a sudden surge of current and voltage that produces the popping sound.
The color code for a 1k resistor is typically
brown-black-red-gold, where each color corresponds to a specific digit or multiplier value. Brown represents the first digit, which is 1, black represents the second digit, which is 0, red represents the multiplier, which is 100 (since it has two zeros after the 1), and gold represents the tolerance, which is +/- 5%.
In terms of the physical size of the resistor, this can vary depending on the wattage rating and other factors. A 1k resistor with a standard 1/4 watt rating, for example, might be around 0.4 inches (10 mm) in length and 0.1 inches (2.5 mm) in diameter. However, larger wattage ratings or different types of resistors (such as surface mount or wirewound) could result in different sizes and shapes.
Overall, the use of a 1k resistor can be an effective way to minimize or eliminate turn-on pop sounds in an amplifier circuit, and the brown-black-red-gold color code is a common way to identify this value of resistor. Resistor Color Code with Tolerance:
Resistors are widely used electronic components that are used to regulate the flow of electrical current in circuits. They have a certain resistance value that is measured in ohms (Ω). To denote this value, resistors have a that is printed on their body. This code consists of four or five colored bands that indicate the resistance value and tolerance of the resistor.
The tolerance of a resistor is the amount by
which its actual resistance can deviate from its nominal value without causing any significant impact on its operation. The tolerance is usually expressed as a percentage of the nominal value. For example, a resistor with a 10% tolerance and a nominal value of 1000 Ω can have an actual resistance value anywhere between 900 Ω and 1100 Ω.
To add a tolerance to the resistor color code, an additional band is added to the end of the existing four-band code. The color of this band indicates the tolerance of the resistor. The tolerance band can be located either to the right or left of the four-band code, depending on the manufacturer.
The following table shows the color codes for the tolerance bands used in the resistor color code:
| Tolerance | Color Code |
| 1% | Brown |
| 2% | Red |
| 5% | Gold |
| 10% | Silver |
| 20% | None |
The color code for a resistor with a 10% tolerance would be a four-band code with the tolerance band at the end. For example, let’s consider a resistor with a nominal value of 2400 Ω and a tolerance of 10%. The color code for this resistor would be:
| Band | Color | Value |
| 1 | Red | 2 |
| 2 | Yellow | 4 |
| 3 | Black | 10^2 |
| 4 | Silver | 10% |
Using the color code, we can determine the resistance value of the resistor as 24 x 10^2 = 2400 Ω. The silver band at the end indicates that the tolerance of the resistor is 10%.
When working with resistors,
it is essential to select the right tolerance value based on the specific application. Resistors with a lower tolerance value are generally more precise but may also be more expensive. In contrast, resistors with a higher tolerance value may be less precise but are also more cost-effective.
It is worth noting that some manufacturers may use different color codes for the tolerance band. Therefore, it is essential to refer to the manufacturer’s datasheet or consult an expert in case of any confusion.
Final words
resistors play a crucial role in electronic circuits, and their resistance value and tolerance are denoted by a color code. Adding a tolerance Mad PCB band to the resistor color code can help determine the deviation of the actual resistance value from its nominal value, ensuring optimal performance of the circuit.
