What happens to resistance of conductor if conductor is heated?

Heat and resistance is directly proportional, in that, when heat goes up, resistance goes up. An example of this is the 'ping' effect when a worn old style incandescent bulb b (MORE)

Can you cut heat resistant glass?

Hi there yess you can cut heat resistant glass all you need is a diamond cutter. A diamond cutter is something window repairers and fitters use it has a small peice of diamo (MORE)

How do you convert from heat input energy to temperature for resistance heating?

It takes approximately 4.184 Joules of heat to raise the temperature of 1 gram of water 1 degree C. 1 Joule is the energy of 1 Watt for 1 second (or 3,600,000 Joules equals 1 (MORE)

What is the most heat resistant element?

Tungsten is the most heat resistant element (3422 degrees Celsius), but when carbon is in its graphite form, it is even more heat resistant (up to 3692 degrees Celsius)
Thanks for the feedback!

What will happen to diode resistance if the diode is heated?

The resistance of a semiconductor junction drops at high temperature due to creation of additional current carriers, electrons and holes, and if the device gets too hot the lo (MORE)

What happens to its resistance when an electrical device is heated?

That will depend on the temperature coefficient of resistance of  the device, which could be positive (i.e. resistance increases with  increasing temperature), negative (i.e (MORE)
