Question

The laws shown in the video—kirchhoff’s junction law and kirchhoff’s loop law—are not newly introduced laws of physics. The junction law is based on __________

Answer 1

The junction law is based on the conservation of charge.

Explanation:

Kirchhoff's current law, or junction law, (1st Law) states that current flowing into a node (or a junction) must be equal to current flowing out of it. This is a consequence of charge conservation—charge is not created or destroyed in a closed system.
