Question

Please answer all of them [True OR False]:-

A- When one applies the Kirchhoff loop rule to a circuit, there is always a electric potential increase across a battery no matter through which direction one walks through it.

B- If there are 5 junction points in a circuit, then 5 junction rule equations are needed to solve for electric currents in the circuit.

C- When one makes use of Kirchhoff's rules equations to solve for electric currents in a circuit, and obtains a negative electric current, that means the calculation is completely wrong.

D- If there are 6 meshes in a circuit, then 6 loop equations are needed to solve for currents in the circuit.

Explanation / Answer

Kirchhoff’s first law states that at any junction in a circuit, the sum of the currents arriving at the junction = the sum of the currents leaving the junction.

Kirchhoff’s second law states that the net electromotive force around a closed circuit loop is equal to the sum of potential drops around the loop.

Kirchhoff’s second law or voltage law is a consequence of the law of conservation of energy.
