Resistors having extremely low tolerance rating are called as.?
jumper
How does temperature affect power rating of carbon resistors?
Its normal power rating is at room temperature. For a temperature of 75 degrees, halve the rating.
How do manufacturers of resistors indicate the value of the resistance?
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.

What is rating of resultant resistor when you add two resistors in series combination?
i dont know the aswer, please answer
The technical experts and nominated COR are usually involved in evaluating the technical merits of the submitted proposals and rating them?
Statement of Work
When all resistors are equal value the total resistance is equal?
This depends on whether your resistors are in serial or parallel. If they are in serial, the value of the resistors just adds up, so : Val(total) = val(single) x n(umber of resistors) If they are in parallel, each added resistor lowers the total value, while the power rating rises : Val(t) = 1/ ( val(s) x n)
What modifier is used to indicate only the technical component was provided?

If you are only given 1 kilo ohms resistors with 0.5 watt power rating how can you construct a resistive load of 1 kilo ohms with 1 watt power rating?
Well...you can't. Not a load with an exact 1 watt power rating. But if you can live with a 2-watt power rating (in a circuit that would be yes--it's called derating and you do it for added life, or because you've already got the parts) you'd connect two resistors in series and set that aside, connect two more resistors in series, then connect the two series networks in parallel. Each series network is rated at 2 kilohms; paralleling the two networks brings you back down to 1 kilohm.
How are resistors classified on the basis of power rating?
The ability of any component part to radiate heat depends partly on the materials it is made from and mainly on its surface area. So, as large-sized resistors have a much bigger surface area than small ones, the power rating of a resistor is made according to the power (Watts) it has been designed to dissipate safely without overheating.
What is meant by star rating for ply in Off the Road tires?
The load capacity of a tire is indicate by the star rating (in case of radial tire) and the ply rating (in cse of bias tire).
Does the size of a resistors make a difference in proving ohm's law?
Nope, resistors all the way from 0 ohms through 100 megohms come in the same package size(s). Different package size depends on power rating of the resistor, high wattage resistors must be much larger than low wattage resistors to allow them to dump the heat and not burn out. Some very high wattage resistors even have plumbing fitting attached so that refrigerated cooling water may run through their outer case to help remove heat!
