The algebraic sum of potential changes in a circuit is zero is Kirchhoff's _ rule.
Correct answer: B. Second.
- A. First.
- B. Second.
- C. Third.
- D. None of these.
Explanation
KVL, Kirchoff's voltage law or Kirchoff's loop rule states that within a closed loop containing multiple emf sources and resistors, their sum would be zero taking the current flow as acw or cw within the loop let's us apply the conventions of the rule to find the value of unknown potential drop/rise.

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.
