What does resistance in wire depend on?
Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
What happens to resistance when length of conductor is doubled without affecting thickness of conductor?
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
Why does the electrical resistivity of a conductor does not depend on its dimensions?
resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length
Difference between gunn diode and pin diode?
gunn diode is transfered electron device & PIN diode is semiconductor device
What is a real diode?
whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.
What is a resistance of a material?
Resistance is the opposition to the flow of electric current. It is affected by the length, cross-sectional area, and resistivity of a material. As resistivity is affected by temperature, temperature indirectly affects resistance.
How many ohms does a 9v produce?
Question is not clear.Is question asking about the battery's internal resistance ?AnswerResistance is not affected by voltage. The resistance of a material depends upon the length, cross-sectional area, and resistivity of that material. As resistivity is affected by temperature, resistance is also indirectly affected by temperature.
Resistance of a copper conductor will decrease with an increase of applied voltage?
Resistance is affected by the length, cross-sectional area, and resistivity of the conductor. The resistivity, in turn, is affected by temperature. So only by changing one of these four factors will the resistance of a conductor change. Changing voltage will have no affect upon the conductor's resistance.
What three primary factors influence electrical resistance of circuit?
The resistance of any material is affected by its length, cross-sectional area, and resistivity. As resistivity varies with temperature, resistance is indirectly affected by temperature.Specifically, resistance is directly proportional to length and inversely proportional to cross-sectional area, and resistivity is the constant of proportionality.These factors apply to the conductors and all the components of your 'circuit' -including any insulation.
Resistance is affected by a material's?
yes. affected by types of material. conductor is a good material. semiconductor is okay but insulator cannot move the charges through it.
Does electrical resistance depend on temperature and bias voltage?
Electrical resistance depends on the temperature but not the biased voltage.AnswerIt's resistivity that can be affected by temperature, which means that resistance is indirectly affected by temperature.
What are four factor that determine resistance?
There are three, not four, factors that determine the resistance of a conductor. These are the length of a conductor, its cross-sectional area, and its resistivity.As resistivity is affected by temperature, you could say that temperature indirectly affects resistance but, strictly, temperature is affecting the resistivity not the resistance -which is why it is not considered a 'fourth' factor.So, resistance = resistivity x (length/area)
What does resistance in wire depend on?
Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
What is the resistivity of graphite?
The resistivity of graphite is 7.837 µΩm.
What happens to resistance when length of conductor is doubled without affecting thickness of conductor?
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
Why diode logic gate is not suitable for cascading operation?
the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
What is thermal resistivity of soils?
Resistivity is the opposite of conductivity. The thermal resistivity of soil is the degree to which soil impedes the flow of heat, or insulates against heat.
