Can you use a potentiometer as a resistor?
Introduction: Wire a Potentiometer As a Variable Resistor
However, by only connecting two pins (one outside pin and one center pin) of a potentiometer to your circuit, you can turn a pot into a variable resistor.
What is the resistance of a 10K potentiometer?
10kΩ resistance
A ’10K Potentiometer’ is a potentiometer that has a 10kΩ resistance. When you move your wiper, this will adjust the variable resistor resistance from 0Ω up to 10kΩ. 10K Potentiometers can come as rotary, linear and many other types of potentiometers.
What type of resistor is a potentiometer?
What is a Potentiometer? A potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element.
What does 10K potentiometer mean?
A 10K Potentiometer is also known as a variable resistor. This Potentiometer is great for controlling the contrast on your LCD. This 10K potentiometer pinout is a variable resistor that can control the contrast on an LCD display.
What are the 4 types of potentiometer?
There are four types of linear potentiometers based on their applications: Slide, Dual side, Multi-turn slide, and Motorised fader potentiometer.
What ohm potentiometer do I need?
How to size a Potentiometer – A Galco TV Tech Tip – YouTube
Can I use a 5K potentiometer instead of a 10k?
You ‘Can’ fudge the value though… if you design for a 10K but the desired result occurs when the potentiometer is set to less than 5K then you can use a 5K… you cannot use lower, and you can most certainly use higher.
Can I use 100K potentiometer instead of 10k?
So a 100K potentiometer has ten times the resistance of a 10K potentiometer. Which one you would choose depends on the application—it’s often a tradeoff between some form of the following two factors: At a given voltage, the 100K pot will draw less current, which could reduce wasted energy and improve battery life.
How do you choose a potentiometer resistance?
In general, you want the potentiometer to be as small as possible without putting too much of a load on the source. A quick rule of thumb for selecting the resistance of a potentiometer is that you want the input impedance to be an order of magnitude (10 times) higher than the output (source) impedance.
Can I use 100K potentiometer instead of 10K?
Can I use a 5K potentiometer instead of a 10K?
How do I choose a potentiometer for my circuit?
The best way to determine the type, or law of a particular potentiometer is to set the pots shaft to the center of its travel, that is about half way, and then measure the resistance across each half from wiper to end terminal. If each half has more or less equal resistance, then it’s a Linear Potentiometer.
Does resistance of potentiometer matter?
Does potentiometer resistance matter? However, the value of the resistance DOES matter to a certain extent. For example, if you used a 10 ohm potentiometer connected across 5 volts, the pot alone would draw 500 milliamperes and dissipate 5 * 0.5 or 2.5 watts (i.e. it would get quite warm and maybe even burn out).
What value potentiometer do I need?
A potentiometer does you no good if it covers a range of zero ohms to 100 ohms but you need it to operate up to 1000 ohms. Conversely, if you need to make adjustments of 10 ohms, you’ll find a range of 1,000 ohms too coarse to adjust.
How do you size a potentiometer?
What are the four types of potentiometers?
Can I use 10k potentiometer instead of 5k?
Replacing the 10k potentiometer with a 5k just means that it will draw a constant 0.5 mA more current, which will not be any problem what so ever.
What are the 5 types of resistors?
Types of Resistors
- Fixed Value Resistors. These are the predominant type of resistor configuration, and as the name suggests, they have a fixed resistance value.
- Variable Resistors.
- Resistor Networks.
- Carbon Film Resistors.
- Metal Film Resistors.
- Wirewound Resistors.
- Metal Oxide Resistors.
- Metal Strip Resistors.
How do I know which resistor to use?
To select a resistor for a specific application, the following steps are recommended:
- 1 . (a) Determine the Resistance.
- 2 . Determine the proper “Watt Size” (physical size) as controlled by.
- 3 .

Does resistance increase power?
When power increases, the resistance also increases, while keeping current I constant. However, when the resistance in the circuit decreases, power in the circuit also decreases, while keeping current I constant.
What are the 4 types of resistors?
How big of a resistor do I need?
A rule of thumb is to find a resistor with twice the power rating. Here I would choose a 250 mW resistor since those are the most standard ones. Usually, you can just use the cheapest resistor you can find with the correct power rating.
How do I choose a resistor?
How do you identify a resistor?
Some resistors have contact plates on the bottom. Read the 3 or 4 numbers on the resistor. The first 2 or 3 represent the significant digits and the last indicates the number of 0s that should follow. For example, a resistor reading 1252 indicates a rating of 12,500 ohms or 1.25 kilo-ohms.
What happens if I use a higher ohm resistor?
The circuit with the higher resistance will allow less charge to flow, meaning the circuit with higher resistance has less current flowing through it.
