Kirchoff's fist law (KCL) is based upon the law of conservation of:
Correct answer: A. Charge
- A. Charge
- B. Energy
- C. Mass
- D. Momentum
Explanation
Kirchhoff's first law is a manifestation of law of conservation of charge, if there is no sink or source of charge at a point, the total total charge flowing towards the point must be equal to the total charge flowing away from it.

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.
