What is the opposition to the current flow?
resistance is the opposition to the flow of electric charge
Why the inductor heat up?
Temperature affects the resistivity of materials which, in turn, affects their resistance. For pure metal conductors, their resistance increases with temperature. As an inductor is often made from a coil of copper wire, its resistance will increase whenever its temperature increases. If it is important for the resistance to remain constant over a wide variation of temperature, then alloys, such as constantin, are used instead of copper. These alloys maintain an approximately-constant resistance over a wide range of temperatures.
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
The electrical resistance of circuit is influenced by three primary factors?
Resistance is directly proportional to the resistivityand length of a material, and inversely-proportional to its cross-sectional area. It should also be noted that its resistivity is affected by temperature, so temperature indirectly affects resistance.
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 the name given to a person who guides an orchestra?
cunductor
What are two affects of resistance?
Heat & power loss.
What affects air resistance?
Fluid density, relative velocity, and object shape affect air resistance.
Would you want a pair of mittens from a cunductor or from an insulater?
Normally from an insulator.
What is the cunductor of heat and electricity of iron?
what is the conductor of heat and electricity of iron
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
