What else can I help you with?
Does increasing potential difference increase resistance?
Resistance is due to a property specific resistance of material. In no way resistance depends on the voltage applied. This is the case of ordinary conductor. But in case of semi conductor or insulator there may be chances to get a variation of conductance and hence resistance due to potential applied.
What will happen to the resistance if the length of the conductor increase?
ERMM THE RESISTANCE INCREASES ) when longer
Does thickness of a metal affect its electrical resistance?
Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
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.
What happen if lay ratio of standard conductor is increase?
Increasing the lay ratio of a standard conductor means increasing the length of lay, which can result in reduced flexibility and increased overall diameter of the conductor. This can impact the handling and installation of the conductor. Additionally, it can affect the electrical performance by increasing inductance and potentially introducing more losses due to skin and proximity effects.
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.
Does resistance increase as the cross-sectional area of the wire?
the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease)AnswerSince resistance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.
Will an increase of applied voltage decrease the resistance of a copper conductor?
No, the resistance is fixed by the cross section and length of the conductor and does not vary with voltage.
What would the resistance of the wire if the resistance is 10 ohms be the same if it were twice as long?
The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms
Does increasing the resistance increase the electric current?
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
What are two ways to increase air resistance of an object?
Increasing the surface area of the object, such as by adding flaps or a parachute, can increase air resistance. Additionally, increasing the object's speed will also increase the air resistance acting on it.
