A pull-up resistor common 4K7 is normally used on ICs where a pin is floating to pull the pin to 5 volt or logic 1 it can be pulled to logic 0 internally by the IC it is normally used with MCUs (micro processors)

∙ 8y agoPull-up resistors are resistors which are used to ensure that a wire is pulled to a high logical level in the absence of an input signal.Pull-up resistors are resistors used in logic circuits to ensure a well-defined logical level at a pin under all conditions.
Pull-down resistors work in the same manner as pull-up resistors, except that they pull the pin to a logical low value. They are connected between ground and the appropriate pin on a device. A pull down keeps the base at ground until the switch closes, which connects the base to Vcc. again without a short.

How does a resister pack work?
resister is nothing but a 'clay' which will reduce the flow of current. There by limiting the volt.
Where is resister used?
To impede the flow of current
What a weak pull up resistor?
A: That refers to a resistor pull up that is not sufficient to do the job that is to pull up. It also means is greater in value that it should be
When Resister is 120 volts and the current through the resister is 0.5 Amps determine the value of the resistor in ohms?
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
Why the net resistance increases in series connection?
series network consists of components i.e resisters connected end to end. since their is only one path for the flow of current. but potential drop across each resister is different. so thats the reason that series network has maximum resistence then the highest resister in combination. the same amount of current passes through each resister.
Why do you need pull up register?
pull up resistor is a one of the dubakur resister
Why you use pull up resister at port-0 in 89c51?
Only port 0 needs pull-up resistors to be connected externally if you want to use it as out put port, because it has no in built pull up circuit so it can't give +5v as out put. refer micro controller and applications book by mahmed ali mazidi.
What is a resister person?
A resister is a person who resists or opposes something.
What is gang resistor?
Group of resister is called as gang resister

What are the first 3 coloured strips on a resister for?
An engineer who knows the secret color code can glance at the resister and instantly know the resistence of the resister in ohms.
What do you means of resister in embedded system?
in embedded system resister means, memory to store the data.
How does a resister pack work?
resister is nothing but a 'clay' which will reduce the flow of current. There by limiting the volt.
How do you change the heater resister on vectra 52 plate you only have full speed?
Take out the glove box there you will see the heater motor the back of that is the resister you will need to get on yyour back to reach up to it.it should slide out
