The Kirchhoff's first law (Σ i = 0) and second law (Σ iR = Σ E), where the symbols have their usual meanings, are respectively based on (a) conservation of charge, conservation of energy (b) conservation of charge, conservation of momentum (c) conservation of energy, conservation of charge (d) conservation of momentum, conservation of charge

Answer: (a). Σ i = 0: charge entering a junction equals charge leaving, so conservation of charge. Σ iR = Σ E: energy supplied equals energy used round a loop, so conservation of energy. So the answer is (a).

Kirchhoff's Laws & Measuring Instruments

The Kirchhoff's first law $\left(\sum i = 0\right)$ and second law $\left(\sum iR = \sum E\right)$ , where the symbols have their usual meanings, are respectively based on

Show answer and solution

Answer: (a)

$\sum i = 0$ : charge entering a junction equals charge leaving, so conservation of charge.
$\sum iR = \sum E$ : energy supplied equals energy used round a loop, so conservation of energy.
So the answer is (a).
