Question

According to Kirchhoff's rules, which of the following is true?

A. The total current into a junction equals the total current out of the junction.
B. The total voltage around a closed loop is always zero.
C. The potential difference across a resistor is inversely proportional to the current passing through it.
D. The resistance of a conductor is directly proportional to its temperature.

Answer 1

According to Kirchhoff's rules, the total current into a junction equals the total current out of the junction.

Step-by-step explanation:

The correct statement according to Kirchhoff's rules is A. The total current into a junction equals the total current out of the junction.

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. The analogy of water flowing in and out of a plumbing junction can be used to understand this concept.
