The electrical resistance of a conductor is dependent on the following factors: The cross-sectional area of the conductor. Length of the conductor. The material of the conductor.
What are the factors affecting resistance class 10?
The resistance of the conductor depends on the following factors:
- The temperature of the conductor.
- The cross-sectional area of the conductor.
- Length of the conductor.
- Nature of the material of the conductor.
What are 4 factors that affect electrical resistance in a load?
There are 4 different factors which affect resistance:
- The type of material of which the resistor is made.
- The length of the resistor.
- The thickness of the resistor.
- The temperature of the conductor.
On what factors does the resistance of a conductor depends Class 10?
The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity.
What factors affect electrical resistance?
There are several factors that affect the resistance of a conductor;
- material, eg copper, has lower resistance than steel.
- length – longer wires have greater resistance.
- thickness – smaller diameter wires have greater resistance.
- temperature – heating a wire increases its resistance.
What is an electrical resistance?
Resistance to electricity–that is, electrical resistance–is a force that counteracts the flow of current. In this way, it serves as an indicator of how difficult it is for current to flow. Resistance values are expressed in ohms (Ω).
What are the factors affecting electric current?
Science Project _ Electric Circuits- factors affecting voltage,amperage, resistance. In a closed electric circuit, resistance of the components and the voltage of a power source are affecting the electric current. Current is the rate of flow of electrons.
Which of the following factors affects the resistance of an object?
How much resistance a material has depends on several factors: the type of material, its width, its length, and its temperature. All materials have some resistance, but certain materials resist the flow of electric current more or less than other materials do. … A longer wire has more resistance than a shorter wire.
Which factor does not affect the resistance in an electric circuit?
The resistance of a conductor does not depend on Pressure.
Conductors show less resistance and Insulators show very high resistance. So it depends on the material. It is inversely proportional to the cross-sectional area of the wire.
What is resistance of a conductor Class 10?
Resistance is defined as the property of a conductor to resist the flow of charges through it. The resistance of conductor is numerically given as the ratio of potential difference across its length to the current flowing through it.
What are the factors on which the resistance of a conductor in the shape of a wire depends?
Answer
- Length of the conductor.
- Area and cross-section of the conductor.
- Effect of the material of the conductor.
- Effect of temperature on the material.
- Nature of the conductor.
What causes resistance in an electric circuit?
An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. … The relationship between resistance and wire length is proportional .
What factors affect resistance of a material select 3 options?
The resistance of a given piece of wire depends of three factors: the length of the wire, the cross-sectional area of the wire, and the resistivity of the material composing the wire.
