How is electrical resistance decreased?
Ways to reduce electrical resistance: increase the diameter of the conductor, decrease or increase the temperature of conductor (depending on its thermal characteristics), decrease the length of the conductor. A change in the material out of which the conductor is made can decrease resistance, too. And there is the phenomenon of superconductivity. In a simple circuit the resistance can be lowered by adding resistors in parallel. The total circuit resistance will then decrease. You can also reduce resistance by substituting resistors of lower value, or by adjusting a potentiometer, or pot, to a lower value.
Can a vacuum is conductor or non conductor?
A vacuum is a non conductor.
Is a capacitor a conductor or semiconductor?
Conductor
Is aluminum a good conductor of heat?
Aluminium is a metal and metals are good conductors of electricity. Metals also tend to conduct heat,sound and energy.
What is meant by PEN conductor when referring to earthing of supply system?
Conductor combining the functions of both a protective earthing conductor and a neutral conductor
Is polythene good conductor?
No, polythene is considered an insulator and not a good conductor of electricity. It has high resistance which limits the flow of electric current through it.
Is polythene a good conductor?
No, polythene is not a good conductor of electricity. It is actually an insulator, meaning it does not allow the flow of electric current easily. This is due to its molecular structure that does not have free electrons to carry charge.
Is polythene a poor conductor of heat and electricity?
Yes, polythene is a poor conductor of heat and electricity due to its molecular structure which does not allow for the easy flow of heat or electrons. This makes polythene an insulating material that is often used to protect against electrical currents and heat transfer.
Is wood thermal conductor?
Wood is a thermal insulator. It is a poor conductor of heat.
Is aluminum an insulator or conductor of thermal energy?
Aluminum is a conductor of thermal energy and electrical energy.
Can heat move easily through a good thermal conductor?
Yes, that is what "good thermal conductor" means.
Is plastic a thermal conductor?
No
Is krypton a good thermal conductor?
No, krypton is not a good thermal conductor. It is a noble gas and has very low thermal conductivity compared to other materials.
A material that conducts thermal energy well is a thermal?
Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.
Is astatine a good thermal conductor?
Astatine is not a good thermal conductor. It is a poor conductor of heat due to its low thermal conductivity, similar to other halogens. This makes astatine a relatively inefficient material for transferring heat.
Is potassium a good thermal conductor?
No, potassium is not a good thermal conductor compared to other materials. It has a relatively low thermal conductivity, meaning it is not efficient at transferring heat.
What is a good thermal conductor?
steel
