What is resistance and resistivity and resistor
Answers
Resistance:
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
Resistivity:
Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.
Materials that conduct electrical current easily are called conductors and have a low resistivity. Those that do not conduct electricity easily are called insulators and these materials have a high resistivity.
Resistor:
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
i hope it will helps you friend
Answer: The resistance is a proportional constant R, is called the resistance of wire.
The SI unit of resistance is ohm.
The resistivity is like resistance it SI unit is ohm-m.
The resistor is like these and it is used to measure the resistance and is resistor will check whether the charge is coming truly or not.
