A typical resistor will burn out when it dissipates power in excess of double its power dissipation rating for an extended period of time.
The power dissipated by a resistor is equal to I2R or E2/R, where
E = the voltage across the resistor
I = the current through the resistor
R = the resistance of the resistor

What happens to the value of a resistor when it goes bad?
we can say that a resistor gone bad if 1. its resistance is different than that printed by the color code 2. doesn't conduct any current Resistors normally will burn open. Carbon resistors almost always do this, while wireound resistors can lower in resistance. They may still allow current flow, but it will not be correct.
What is the advantage of film resistors over carbon resister?
Film resistors have lower noise than carbon resistors.
When resistors are connected in series then what happens to the watt?
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
What is a pull up resister?
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)
What is your observation of resistors in series?
I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
What is resistence tolerence?
The typical spread (deviation) from the nominal value of the resistance of several resistors.
What seems to be the typical educational level?

The typical education level is low.
How can you fix a heater and AC fan that only work on high?
Resistors control the speed of the AC/Heater fan. These resistors are switched on and off in various combinations to create the different fan speeds. When the resistors burn out your fan will only work on the "HI" setting. The "HI" setting doesn't use any of the resistors and that's why it works. These resistors are near the blower and the blower is beneath the dashboard on the pasenger side. Just have to located resistors now.

How do you repair an air conditioner on a 1996 Nissan Sentra that only works on level 4 and nothing happens on levels 1 2 and 3?
A resistor block controls the speed of the AC/Heater fan. These resistors are switched on and off in various combinations to create the different fan speeds. When the resistors burn out, your fan will only work on the "HI" setting. The "HI" setting doesn't use any of the resistors and that's why it works. These resistors are near the blower and the blower is beneath the dashboard on the pasenger side. A/C is probably fine. If you try the heater, it will show the same problem as your question.
Is level 5 good for a yr 6?
Yes, level 5 is good for a year 6. Here is a simple table to show you the expectations of a child: Level W Working towards level 1, very weak Level 1 Average for a typical 5 year old Level 2 Average for a typical 7 year old Level 3 Average for a typical 9 year old Level 4 Average for a typical 11 year old Level 5 Average for a typical 13 year old Level 6 Average for a typical 14 year old Level 7 Above average for typical 14 yr old Level 8 Only available in maths Hope this helps :) http://www.satsguide.co.uk/what_are_sats.htm
What would happen to the power dissipated in the voltage divider?
'Power dissipation' in a voltage divider describes the rate at which energy is transferred from the resistors to the surrounding atmosphere through heat transfer, due to the work done on the resistors by the current flowing through them. If the work done on the resistors causes their temperature to increase faster than heat transfer takes place (a function of the surface area of the resistors), then they will overheat and, possibly, burn out.
Why do you need 330 ohm resistor for LED?
Generally 330ohm resistors are used to power a typical 3 volt LED if the source voltage is 5v
What are those materials of resistors?
most of the resistors commonly used are carbon resistors

What is the chemical test for hydrogen?
Hydrogen burn in air releasing a typical sound.
