Whose law states that at a junction in an electric circuit, the sum of the currents flowing into the junction is equal to the sum of the currents flowing out of the junction?
Show Answer
Answer
D. Gustav Robert Kirchhoff
Show Explanation
Explanation
Kirchhoff’s junction rule expresses charge conservation: in a steady circuit, the total current entering a junction equals the total leaving it. Ohm’s law relates voltage, current and resistance; Faraday’s law concerns induction.
