The basic unit for electric current is:

Question

BlackTom AI · Accepted Answer

Consider the fundamental units used in physics to measure different physical quantities.
Option a: Kilogram is the basic unit of mass. It is defined to quantify how much matter an object contains, not the flow of electric charge.
Option b: Mole is the basic unit for the amount of substance. It counts the number of elementary entities, such as atoms or molecules, and does not pertain to electric current.
Option c: Ampere is the basic unit of electric current. It measures the rate of flow of electric charges through a conductor, and is the standard unit used in describing current in circuits.
Option d: Kelvin is the basic unit of thermodynamic temperature. It characterizes how hot or cold a system is, independent of electrical phenomena.
Thus, each of the other options corresponds to a different physical quantity (mass, amount of substance, temperature), while Ampere uniquely represents electric current, which is why it is the correct choice.
