Assertion Total current entering a circuit is equal to leaving the circuit by Ki
Assertion Total current entering a circuit is equal to leaving the circuit by Kirchhoff's law. Reason It is based on conservation of energy.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
- C. Assertion is correct but Reason is incorrect.
- D. Both Assertion and Reason are incorrect.
Step-by-step solution
Kirchhoff's current law (KCL) states that the total current entering a junction equals the total current leaving the junction, which is based on conservation of charge, not conservation of energy. The assertion is correct, but the reason given is incorrect because KCL is derived from charge conservation, not energy conservation.
