Question

Kirchoffs first rule ∑I = 0 and second rule ∑IR = ∑E (where the symbols have their usual meanings) are respectively based on ______.

Options

• conservation of momentum and conservation of charge

• conservation of energy, conservation of charge

• conservation of charge, conservation of momentum

• conservation of charge, conservation of energy

Answer 1

Kirchoffs first rule ∑I = 0 and second rule ∑IR = ∑E (where the symbols have their usual meanings) are respectively based on conservation of charge, conservation of energy.

Explanation:

Kirchhoff's First Rule (∑I = 0) is based on the conservation of charge, stating that the total current entering and leaving a junction is equal.

Kirchhoff's Second Rule (∑IR = ∑E) is based on the conservation of energy, ensuring the total energy supplied in a loop equals the energy dissipated.
