The unit for electric current is
Correct answer: D. Coulomb/second.
- A. Erg/second.
- B. Joule/second.
- C. Dyne/second.
- D. Coulomb/second.
Explanation
The unit for electric current is the ampere, which is equivalent to one coulomb of charge passing through a point in a circuit per second. Thus, the correct unit for electric current is coulomb/second. The other options represent units for power and force, not electric current. Erg/second and joule/second are units of power (with joule/second being more commonly known as a watt), and dyne/second is a unit of force.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
