Question:

Choose an incorrect statement from the following about Kirchhoff's rules of electric circuits:

Options:

ΣΙ=0 shows that charge is conserved (Junction rule)

ΣV=0 shows that energy is conserved (Loop rule)

Two rules can be applied to any electrical circuit

Both the rules can only be used if the temperature is constant

Correct Answer:

Both the rules can only be used if the temperature is constant

Explanation:

The correct answer is Option (4) → Both the rules can only be used if the temperature is constant

Kirchoff's rules, do not require the temperature to be constant for their application. The only condition needed is that the circuit must be in steady state, where voltage and currents are constant.
