Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
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.
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
Define zero ohm resistor.?
A zero-ohm resistor does not exist, so we are talking about an ideal resistor. An ideal resistor is needed for description in a circuit, where we lump all wire/parasitic resistances into discrete resistors, but the wire joining two discrete resistors is considered to have no resistance. My definition: a zero-ohm resistor is an ideal resistor that does not consume energy when a current exists in the resistor. Alternatively, a zero-ohm resistor is an ideal resistor that cannot sustain any potential drop when a current is on. Thirdly, a zero-ohm resistor is an ideal resistor that will conduct an infinite current when a voltage is applied across it.
2 resistors unequal value are in parallel. Would the power dissipated by the resistor with larger ohmic value be greater than the power dissipated by the resistor of lesser value?
No, because the power dissipated in a resistor is proportional to the square of the current through the resistor but only directly proportional to the resistance of the resistor (I^2 * R) and the current through the lower value resistor will be higher than the current through the higher value resistor, the lower value resistor will usually dissipate more power.
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
Where is the blower motor resistor on a 1998 f-150?
The blower motor resistor is located under the front dash on the passenger side of the truck. It is a fairly simple job to replace...maybe 15 minutes.

How do you change blower resistor on BMW 523i 1997?
the blower resitor is located behind the dashboard, to access it remove the plastic trim panel under the glovebox, one shoudl see the connector and back of the resistor when looking up and left, just push the tab aside and remove the resistor, the job is very easy and a experienced tech can do the job in about 5mins. good luck.
How do you remove blower motor resistor?
Type your answer here... Remove the plastic cover under the glove box, if equipped and remove the 2 small screws in the resistor and unplug the wire. Very simple job.
Where is the blower motor resistor on a 2001 impala?
It's located up inside of the blower motor housing under the dashboard. I also have included a link to a video that will show you how to get to the resistor and also the tools that you will need for the job.
Is Light dependent resistor an example of resistor?
yes, a variable resistor
Do the blower motor resistor in fords and the blower motor speed controller in Lincolns do the same basic job?
Yes, but not sure if the parts are interchangeable.
How do you change the blower resistor on 2003 ZTW focus wagon?
Drop the glove box by pressing the sides one at a time. The glove box will fall open almost to the floor. Looking behind is the blower houseing and to the left of it is the resistor held in by a phillips screw. Remove the plug and screw and resistor. Install in the reverse. Not a hard job at all. Good Luck.
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
Describe the purpose of the coloured bands on a resistor?
The purpose of colored bands on a resistor is to tell whoever is installing the resistor the amount of resistance that particuliar resistor has.
