Question

According to Kirchhoff's Rules, which of the following is true? Select all that apply.

A. The currents into a junction must equal the currents out of a junction.
B. The total currents around a complete circuit loop must add to zero.
C. The total change in potential around a coholete circuit loop must add to zero.
D. Potential drops into a junction must equal the potential drops out of a junction.

Answer 1

Kirchhoff's first rule states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction. Kirchhoff's second rule states that the sum of changes in potential around a closed circuit loop must be zero.

Step-by-step explanation:

Kirchhoff's first rule, also known as the junction rule, states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction. This is based on the law of conservation of charge. Kirchhoff's second rule, also known as the loop rule, states that the algebraic sum of changes in potential around any closed circuit path (loop) must be zero. This rule is based on the law of conservation of energy.
