Question

Name the physical quantity of which the unit is coulomb :

• A. capacitance
• B. charge
• C. current
• D. inductance

Answer 1

The correct option is B charge

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges: positive and negative. Positively charged substances are repelled from other positively charged substances, but attracted to negatively charged substances. Negatively charged substances are repelled from negative and attracted to positive. An object is negatively charged if it has an excess of electrons, and is otherwise positively charged or uncharged.
The SI derived unit of electric charge is the coulomb (C).
