What is the purpose of the 10K variable resistor?
Simply put, a variable resistor is able to have its electrical resistance adjusted. These devices are used when working with electrical circuitry because they help to control voltage and/or currents. They specifically work with voltage and currents that are a part of the circuit.
What is a 10K potentiometer used for?
Potentiometers are very useful in changing the electrical parameters of a system. It is a single turn 10k Potentiometer with a rotating knob. These potentiometers are also commonly called as a rotary potentiometer or just POT in short.
How much current can a 10K potentiometer?
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 LDR do?
LDRs (light-dependent resistors) are used to detect light levels, for example, in automatic security lights. Their resistance decreases as the light intensity increases: in the dark and at low light levels, the resistance of an LDR is high and little current can flow through it.
Can I use 10k potentiometer instead of 50K?
The main difference is the impedence of the pot. If I am correct in thinking this, the 10k will get louder faster since it has less resistance on the voltage. However, some sources may not appreciate driving a 10k ohm load, so 50k helps here.
How much voltage can a potentiometer handle?
The easiest way to think about it is that there is a maximum current through the pot. If you have a 1W 100 ohm potentiometer, the max. current is 100mA (full voltage = 10V); if you are using only 27 ohms of the potentiometer then the max.
Is potentiometer and variable resistor the same?
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.
What the difference between a resistor and a variable resistor?
A resistor limits the passage of electrical current. A fixed resistor has a resistance that does not change. A variable resistor is used in some dimmer switches and volume controls.
What’s the color of a 10K ohm resistor?
Real value Of 10k ohm Resistor Color Code (with tolerance): The multimeter reads slightly more or less the value of the actual 10k resistor color code. This is because the 10k resistor color code last band tolerance value reads as a gold band which is 5%. Also check, 10k smd resistor
What’s the last band of a 10K resistor?
The multimeter reads slightly more or less the value of the actual 10k resistor color code. This is because the 10k resistor color code last band tolerance value reads as a gold band which is 5%.
What kind of resistor has 5 colour bands?
Such registers are called carbon composition resistors. The other types of resistors are carbon film resistors, metal film resistors, and wire-wound resistors. The colour code of the resistor indicates the value of resistance and its percentage reliability for tolerance. But nowadays register also has five colour band on its outer casing.
What does the 3rd band on a resistor mean?
The 3rd band in the case of 4 band resistor band represents the multiplier ( and 4th band in case of 5 band resistor represents the multiplier ). Tolerance can be +-. 2 %. 5 %. 10 %. 20 %.
