Choose an incorrect statement from the following about Kirchhoff's rules of electric circuits:
- A \( \sum I = 0 \) shows that charge is conserved (Junction rule)
- B \( \sum V = 0 \) shows that energy is conserved (Loop rule)
- C Two rules can be applied to any electrical circuit
- D Both the rules can only be used if the temperature is constant
Answer & Solution
Correct Answer
(D) Both the rules can only be used if the temperature is constant
Step-by-step Solution
Detailed explanation
Kirchhoff's rules are based on the fundamental laws of conservation of charge and energy, which are independent of temperature. While temperature may change a component's resistance, the sum of currents at a junction and the sum of voltages around a loop will always be zero. D)…
