Electric charge is measured in
(A) Coulombs
(B) Ampere
(C) Volts
(D) Watts

Hint Coulombs is the SI unit of charge. Ampere is the SI unit of electric current. Volts is the SI unit of potential difference. Watt is the SI unit of power .

Complete Step-by-step Solution Electric charge is the property of matter due to which it experiences a force when placed in an electromagnetic field. The electric charge is of two types- positive electric charge and negative electric charge . Electrons constitute the negative charge while protons constitute the positive charge . Charge is the property of a substance. In general, the sum of electric charges of an isolated system remains constant. When one body loses charge ,the other acquires it. Each electric charge has some electric field associated with it . Like charges repel each other while unlike charges attract each other.

The scientist Charles Augustin de Coulomb gave the very famous coulombs’ law which states that the force between two electric charges is directly proportional to the product of magnitude of charges and inversely proportional to the square of distance between them .
The unit of electric charge was named after him. That is why the unit of electric charge is coulombs.

Hence, the correct option is A.

Note- The unit of electric charge was named after the scientist who invented it. Each electric charge has some electric as well as magnetic field associated with it.
