100k Resistor: Understanding the Basics
A 100k resistor is a type of electrical component that plays a vital role in electronic circuits. It is a passive component that reduces the voltage or current in a circuit, and its resistance value is measured in ohms (Ω). In this article, we will delve into the world of 100k resistors, exploring their characteristics, applications, and uses.
What is a 100k Resistor?
A 100k resistor is a resistor with a resistance value of 100,000 ohms or 100 kilohms. It is denoted by the symbol "R" and has a specific color code, which indicates its resistance value. The color code for a 100k resistor is typically brown, black, and orange.
Characteristics of a 100k Resistor
Resistance Value
The primary characteristic of a 100k resistor is its resistance value, which is 100,000 ohms. This means that it can reduce the voltage or current in a circuit by a factor of 100,000.
Power Rating
The power rating of a 100k resistor determines the maximum amount of power it can handle without overheating or damaging the component. Common power ratings for 100k resistors include 1/4 watt, 1/2 watt, and 1 watt.
Tolerance
The tolerance of a 100k resistor refers to the margin of error in its resistance value. A tolerance of ±1% or ±5% is common for 100k resistors.
Applications of 100k Resistors
100k resistors are used in various electronic circuits and devices, including:
