Answer 1

Answer:

A.The ohm is defined as an electrical resistance between two point of a conductor.

B. same answer follows for B

C. I unit of electrical current equal to a flow of one coulomb per second

D. 1 volt is defined as energy consumption of 1 joule per electric charge of one coulomb.

E. same answer follows for number E.

Answer 2

a) It is the property of conductors to oppose the flow of charge through it.

b) It is the resistance offered by conductors of unit length and unit area of cross section

c) It is rate of flow of charge in the conductor.

d) It is the SI unit of potential difference.

e) It is the amount of work done to move 1 unit positive charge from one point to another.
