What factors effect the resistance of a conductor?
Factors affecting the resistance of a conductor include the material from which it is made, its length, its cross-sectional area, and its temperature.
What 4 things affect resistance?
The four things that affect resistance are the material of the conductor, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor.
Which two effects are always present in current flow?
Resistance and temperature rise are two effects that are always present in current flow. Resistance causes a drop in voltage and limits the flow of current, while the flow of current through a conductor generates heat causing a rise in temperature.
What is effect of temperature on conductor?
Increasing the temperature of a conductor will typically increase its electrical resistance, reducing its conductivity. This is due to increased collisions between electrons and atoms in the conductor, hindering electron flow. Extremely high temperatures can cause a conductor to ultimately melt or break down.
When current passes through a conductor what makes the conductor heat up?
When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
Why the resistance of conductor rise with the rise of temperature?
When the temperature of a conductor is increased, the amplitudd of vibrations of atoms increases.As a result, the probability of collision of electrons with vibrating atoms increases.That is why, it is said that the resistance of a conductor is increases with increasing temperature
Why does resistance of a conductor rise with temperature?
When the temperature of a conductor is increased, the amplitudd of vibrations of atoms increases.As a result, the probability of collision of electrons with vibrating atoms increases.That is why, it is said that the resistance of a conductor is increases with increasing temperature
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
What factors effect the resistance of a conductor?
Factors affecting the resistance of a conductor include the material from which it is made, its length, its cross-sectional area, and its temperature.
What affects the resistance of an electric conductor?
The material from which the conductor is made, the length of the conductor, the diameter of the conductor and the temperature of the conductor are all things that impact its resistance.
If pressure is constant and current increases the resistance?
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
What 4 things affect resistance?
The four things that affect resistance are the material of the conductor, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor.
Why does the resistance of a conductor rise with the rise in temperature?
For metals, as the temperature rises, the atoms wiggle around more, and are more likely to be hit by an electron that is moving through the metal. The more electrons that hit the atoms, the greater the resistance. Think of the wiggling atoms as interfering with the smooth flow of electrons.
Which two effects are always present in current flow?
Resistance and temperature rise are two effects that are always present in current flow. Resistance causes a drop in voltage and limits the flow of current, while the flow of current through a conductor generates heat causing a rise in temperature.
If the temperature of a metal conductor increases the electrical resistance of the conductor usually?
increases
What is thermistorhow is it works?
A thermistor is a temperature sensitive resistor, there are two types: 1) If the temperature rise the resistance will go higher 2) If the temperature rise the resistance will go lower
