What is 10K variable resistor?

The 10K Potentiometer Product Description: This adjustable or Variable resistor are PCB mountable and has 3 terminals. The voltage between the terminal varies as the preset is rotated. The Variable resistors are used for variation voltage as per the need in a circuit.

What is a 10K potentiometer used for?

The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.

What is the difference between a variable resistor and a potentiometer?

In the potentiometer the resistance of the track remains the same as the wiper moves, and only the potential on the wiper changes. In a variable resistor the resistance of the track apparently changes as the wiper moves and short circuits more or less of the track resistance.

How much voltage can a 10k potentiometer handle?

If the potentiometer is rated at 1 Watt, you can only apply a maximum of 100 volts. I.e 10 mA. That applied to the voltage across the full 10000 ohms. That also means that you cannot pass more than 10 mA into the Wiper.

What does a 1K resistor look like?

1 K Ohm colors are – Brown – black – red Here is the color coding chart to determine the resistor values Resistors with four bands are > 1% tolerance resistors. Resistors with 5 band are 1% tolerance resistors. First three bands determine the value of the resistor.

Can I use 10k potentiometer instead of 50k?

It will work in a way that you will increase input resistance, but you will loose gain. Adding 10k resistor before the 10k pot will lower signal by 6dB. Depending on your source, you may not need any adjustements at all and 10k pot will work equally well as your 50k.

What does a variable resistor do?

Variable resistor A resistor limits the passage of electrical current. A fixed resistor has a resistance that does not change. The resistance of this resistor is changed by moving the position of a slider. A variable resistor is used in some dimmer switches and volume controls.

Does a potentiometer reduce voltage?

When the potentiometer resistance is decreased (the wiper moves downwards) the output voltage from pin 2 decreases producing a smaller voltage drop across R2. Likewise, when the potentiometer resistance is increased (the wiper moves upwards) the output voltage from pin 2 increases producing a larger voltage drop.

How much power can a potentiometer handle?

Most potentiometers I have found are rated for 1/2W or 1W. A general rule of thumb though is that you shouldn’t be putting much power through it anyway – it should only be controlling a small signal. Please note that the power rating of a potentiometer is for the entire end-to-end resistance.

What does a 10k ohm resistor look like?

What does a 10K ohm resistor look like? A 10k ohm resistor has 4 color bands: brown, black, orange, and gold for 5% tolerance, respectively. A 1k ohm resistor has 4 color bands: brown, black, red, and gold for 5% tolerance, respectively.
