Combination of Resistors: Practice Problem & Solution

Pick out wrong statement about the Kirchhoff's laws of electric circuit.
Outgoing currents adds up and are equal to incoming currents at a junction
Starting with any point if we come back to same point, total potential change must be zero
Junction rule is based on conservation of energy law
Bending or reorienting the wire does not change the validity of Kirchhoff’s junction rule.

Solution Explained:

To solve this problem, we apply the core principles of Combination of Resistors. Understanding the underlying formula is key to arriving at the correct answer below:

Kirchhoff's first law (the junction rule) is based on the law of conservation of charge, not energy. The second law (loop rule) is based on the conservation of energy.
