CONCEPT:

Quantity SI Unit Definition
Electric Charge Coulomb (C) Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
Electric Current  Ampere (A) It is the rate of flow of electric charge past a point or region.
Electric Potential Volt (V) It is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.
Electrical Resistance Ohm (Ω) The electrical resistance of an object is a measure of its opposition to the flow of electric current.
  • The Correct Answer is Option (3) i.e. 1-d, 2-c, 3-b, 4-a.
