Question

The junction rule describes the conservation of which quantity?

1) Charge
2) Energy
3) Momentum
4) Mass

Answer 1

The junction rule in physics pertains to the conservation of charge, ensuring that charge is neither created nor destroyed within a junction in an electric circuit.

Step-by-step explanation:

The junction rule in physics describes the conservation of charge. According to this rule, the total charge entering a junction in an electric circuit must equal the total charge leaving the junction. This conservation law indicates that charge cannot be created or destroyed within an isolated system. The junction rule is a reflection of a more general principle in physics, which includes the conservation of other quantities such as energy, momentum, and angular momentum.
