What is ment by a resistance of conductor ? name and define its sI unite. list the factors on which the resistance of a conductor depends. how is thr resistance of a wire affected if its length is doubled and its radius is doubled?
Answers
resistance is the property of a conductor to resist the flow of charges in a circuit
SI UNIT OF RESISTANCE IS (OHM)
FACTORS ON WHICH IT DEPENDS ARE
1.TEMPERATURE AND NATURE OF MATERIAL
2.IT IS INVERSELY PROPORTIONAL TO THE CROSS SECTIONAL AREA
3.IT IS DIRECTLY PROPORTIONAL TO LENGTH OF THE CONDUCTOR
Here is your answer..
Resistance is defined as the obstacle or something that opposes the flow of current. It's S.I.unit is ohm.
resistance of a conductor depends upon the following factors :-
(1) . length :- resistance of a conductor is directly proportional to its length.
(2). area :-resistance of a conductor is inversely proportional to its cross sectional area.
mainly these are the two factors on which resistance depends
if length is doubled and its radius is also doubled then resistance will be 1/2 of normal resistance....
hope this will help you...
if it is helpful then plzz mark it as brainliest....
