Question

list 3 differences between resistance and resistor​

Answer 1

Answer:

Resistance

1)Material’s property that provides an obstruction to the flow of current

2)Formula R = V/I or,

R = ρ(L/A)

V = Voltage, I = Current, ρ = Resistivity

3) Temperature, Length, Cross sectional area of conductor

4) Resistance’s property is useful in sensors, fuses, heaters etc

5) SI Unit Ohms

Resistivity

1) Resistance of a material having specific dimensions

2) Formula ρ = (R×A)/L

R = Resistance, L= Length, A = Cross-sectional area

3) Resistivity is effective as a quality control test

4) Dependence on temperature

5) SI unit Ohms-meter

Answer 2

$\bold{ \blue{answer}}$

$\: resistor \: and \: resistance \: differences$

a resistor is an electrical component with a predetermined electrical resistance like 1 ohm, 10 ohm, 100 ohm, 10000 ohm,etc.....,

resistance os the property of a conductor which determines the quality of current that passes through it when a potential differenceis applies across it
