What is the value of the resistance when both length and diameter are double?
Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.
A piece of wire 100 m long has a diameter of 1 mm with a resistance of 2 ohms calculate the resistance of the same wire 2 km long with the same current?
If the wire length is 100m and the Diameter is 1mm calculate the Resistance of wire?
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
Which conductor size has the largest diameter?
The largest conductor listed in the National Electrical Code is a 2000 kcmil.
Why the cable size is expressed in Sqmm not in diameter regardless of single or stranded conductor?
The cross-sectional area is one of the factors that determines how much current a conductor can carry -this is regardless of the shape of that conductor's cross section (many conductors are not circular). So the diameter is of not much interest.
What happens to the resistance of the conductor if the conductors become longer but the diameter stays the same?
If the length of the conductor increases while the diameter remains constant, the resistance of the conductor will increase. Resistance is directly proportional to the length of the conductor, so a longer conductor will have higher resistance. The diameter, however, does not directly affect resistance as long as it remains constant.
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.
What is the value of the resistance when both length and diameter are double?
Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.
What would be the effect of resistance of a conductor of doubling its diameter?
doubles
Do thick wires have high or low resistance?
Low resistance.AnswerSince resistance is inversely proportional to the cross-sectional area of a conductor, increasing the diameter ('thickness') of a conductor will reduce its resistance.For example, doubling the diameter of a circular-section conductor will quadruple its cross-sectional area, and reduce its resistance by one quarter.
Does drift velocity of electron depend on diameter of conductor?
No, the drift velocity of electrons in a conductor does not depend on the diameter of the conductor. It is primarily influenced by the electric field applied across the conductor and the mobility of charge carriers within the material. The diameter of the conductor typically affects the resistance of the material, but not the drift velocity of electrons.
When the diameter of a conductor is doubled what happens to its resistance?
Resistance will decreases... Because R is inversely proportional to Area of the conductor.AnswerIf the conductor has a circular cross-sectional area, then doubling the diameter will reduce the resistance to one quarter of its original distance. This is because area is proportional to the square of the radius, and resistance is inversely proportional to cross-sectional area.
What has the least amount of resistance a semi conductor insulator resistor or a conductor?
A conductor has the least amount of resistance among the options provided. Conductors have low resistance due to their ability to easily conduct electricity through the movement of electrons. Conversely, insulators have high resistance, while semiconductors and resistors can have varying levels of resistance depending on their composition and structure.
A piece of wire 100 m long has a diameter of 1 mm with a resistance of 2 ohms calculate the resistance of the same wire 2 km long with the same current?
If the wire length is 100m and the Diameter is 1mm calculate the Resistance of wire?
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.
What is the diameter of a 1.04 m length of tungsten wire whose resistance is 0.19?
The resistance of a wire is not sufficient information to determine its diameter. The diameter of a wire is typically needed to calculate its resistance using the formula R = ρ*L/A, where ρ is the resistivity, L is the length, and A is the cross-sectional area. You would need to know the resistivity and material of the wire to calculate its diameter.
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
