What is meant by electric resistance of a conductor?
svcvcc
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
What factor affects the resistance of a conductor?
This are the factor which affect resistance of a conductor (1). Area of conductor (2). Length of conductor (3) Temperature (4). Type or substance of material used in conducting the electricity.
What is the term used for the hindrance a conductor creates to the flow of electric current?
Resistance is the hindrance a conductor creates to the flow of electric current
What is the path that an electrical current travels?
electric current
What is the opposition to the current flow?
resistance is the opposition to the flow of electric charge
Why does Resistance decrease in thin wire?
Area of cross section: Resistance R is inversely proportional to the area of cross section ( A) of the conductor. This means R will decrease with increase in the area of conductor and vice versa. More area of conductor facilitates the flow of electric current through more area and thus decreases the resistance. This is the cause that thick copper wire creates less resistance to the electric current.
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 a material that will carry an electric current called?
A material that will carry an electric current is called a conductor. Conductor materials have high electrical conductivity, allowing the flow of electric charges with minimal resistance. Examples of conductors include metals such as copper, aluminum, and silver.
What are the factors that affect resistance?
The factors are: length, cross-sectional area and nature of substance.
What affects the resistance of a conductor?
The length and the material that the conductor is made from. Different wire sizes have different ohm/foot. The longer the length of the conductor the higher the ohms/foot. Temperature also affects the resistance. Silver has the least resistance, followed by Copper, then Gold, then Aluminum. Here are some published resistances in micro ohm-cm: Silver - 1.6 Copper - 1.7 Gold - 2.2 Aluminum - 2.7
What affects the amount of electric energy an appliance uses?
Its resistance.
