Question

In the context of the loop and junction rules for electrical circuits, a junction is: Group of answer choices where a wire is bent. where three or more wires are joined. where only two wires are joined. where a wire is connected to a resistor. where a wire is connected to a battery.

Answer 1

Answer:

In the context of the loop and junction rules for electrical circuits, a junction is where three or more wires are joined.

Explanation:

A point where at least three circuit paths meet i.e wires, is referred to as a junction.

Kirchhoff’s circuit laws are two(2) equations first published by Gustav Kirchhoff in 1845. Fundamentally, they address conservation of energy and charge in the context of electrical circuits. One of the laws known as Kirchoff's Current Law deals with the principle of application of conserved energy in electrical circuits. Kirchoff's Current Law states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction.

This basically means, the algebraic sum of currents in a network of conductors(wires) meeting at a point is equal to zero

Answer 2

A junction is a point where at least three circuit paths meet.

A branch is a path connecting two junctions .

Kirchhoff's circuit laws

This law states that, for any node (junction) in an electrical circuit ,

the sum of currents flowing into that node is equal to the sum of

currents flowing out of that node.

Kirchhoff's circuit laws are two equalities that deal with the current

and potential difference in the lumped

element model of electrical circuits .

Some terms associated with Kirchhoff's circuit laws

resistor : An electric component that transmits

current in direct proportion to the voltage

across it.

electromotive force: (EMF)—The voltage

generated by a battery or by the magnetic force

according to Faraday’s Law. It is measured in

units of volts (not newtons, N; EMF is not a

force).

capacitor : An electronic component consisting

of two conductor plates separated by empty

space (sometimes a dielectric material is

instead sandwiched between the plates), and

capable of storing a certain amount of charge.
