The basic relation to calculate resistance tells us:
R = rho*l/A
with
R = resistance [Ohm]
rho = resistivity [Ohm*meter]
l = length [m]
A = surface area [m^2]
So, the resistance (given a certain resistive material) merely depends on the ratio between the length and the surface area of a resistor. Resisotrs tend to be bigger if they have to dissipate more power, for mor heat needs to be lost.
What else can I help you with?
Is resistance an intensive property?
No, it depends upon quantity of matter so is extensive property.
How we can find dimension of resistance?
The dimension of resistance can be found using Ohm's Law, which states that voltage (V) equals the product of current (I) and resistance (R), expressed as V = IR. The dimensions of voltage are [ML²T⁻³I⁻¹], and the dimensions of current are [I]. Rearranging the equation to solve for resistance gives us R = V/I, leading to the dimension of resistance as [ML²T⁻³I⁻²].
Does resistivity depends upon dimension of the conductor?
Yes, resistivity does depend on the dimensions of the conductor. The resistivity of a material is an intrinsic property, but the resistance of a conductor is also influenced by its dimensions such as length, cross-sectional area, and shape. These dimensions affect the resistance of the conductor through the formula R = ρ * (L/A) where ρ is resistivity, L is length, and A is the cross-sectional area.
What will be the effect on specific resistance if length of wire is halved?
it will not effect it because it only depends upon property of medium
What should the value of the resistance box for a 5 hp slipring induction motor?
its depends upon rotor voltage and current
Is resistivity depends upon dimension of conductor?
Yes, resistivity is dependent on the material of the conductor, not its dimensions. Resistivity is an intrinsic property of a material that influences its ability to resist the flow of electrical current.
What is the standard dimension for a kitchen?
depends on who you are
What three factors affect how much electrical resistance an object has?
Any load would do or anything that has resistance. Which is pretty much everything you can hook up to a circuit. For example, lightbulb, buzzer, resistor etc.
What are the factors on which the heat produced the electric current depends upon?
It depends on1 the resistance of wire.2the voltage between the ends of the wire.3the flowing current time.
What is the dimension of radius in unit and measurements?
The dimension is one of length. The value depends on the specific case.
Which is not a force weight air friction resistance momentum?
Momentum is not a force. Momentum is a property of a moving object that depends on its mass and velocity. Forces, such as weight, air resistance, and resistance, act upon objects to change their momentum.
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
