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 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.
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.
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 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.
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
If the temperature of a metal conductor increases the electrical resistance of the conductor usually?
increases
What is effect of temperature on conductor?
It depends on the material. In metals, the resistance increases with temperature.
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 factor affects the resistance of a conductor?
This are the factor which affect resistance of a conductor (1). Area of conductor (2). Length of conductor (3) Temperature (4). Type or substance of material used in conducting the electricity.
Name four factors affecting the resistance of a conductor?
area of the conductor, length of the conductor and temperature around the conductor..........
