A "pull-up" resistor is a resistor used to to perform a specific electronic function - it is not a different type of resistor. A very small current flows through a pull-up resistor so it does not need to be high wattage (1/8 watt is generally fine). The value of a pull-up resistor depends on the resistance of the sensor. If it is simply on or off (no resistance) then a typical pull-up resistor might be 10k ohms.

Diff between weak and strong pull up resistor?
A strong pullup means using small value resistor for pull up whereas a weak pullup means using high value resistor for pulling the signal to Vcc. A strong pullup reduces the RC time constant. Soumen C
How you make NOT gate by using X-OR gate?
Tie unused input high through pullup resistor.
Is a pullup the same as a diaper?
A pullup can be considered a kind of diaper The main difference between a pullup and a normal diaper is that a pullup can be easily pulled on and off in the manner of normal underwear. Additionally, many pullups don't hold as much urine as a normal diaper.
Need of negative logic?
There are many reasons that one might prefer to use negative logic in some or all of a design, a few of these are:discrete switch closure inputs - closing the switch grounds the line (true), opening a pullup resistor pulls the line high (false)multisource signals can be "wire ored" using open collector/drain outputs and a single pullup resistor, instead of needing many actual or gate devicesetc.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
Where can you buy a pullup bar in Bulgaria?
nowhere
Why you use pull up resistor in microcontroller 8051?
Some devices are internally either in the open drain or in the open collector configuration. So in order to create a closed path for the current the device is pulled up with a resistor to the supply.
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
Difference between variable resistor and rheostat?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
What is different between rcj8y and cj8y?
rcj8y has a built in resistor to protect electronic ignitions from spurious signals also to reduce interference to TVs etc. i.e. the R in the plug designation indicates resistor.
What is the difference between a nkg dpr8ea9 and the dp8ea9?
dpr8ea9 is a resistor plug dp8ean is non resistor.
