NEET2013PhysicsCurrent ElectricityActual
Assertion : Total current entering a circuit is equal to leaving the circuit by Kirchhoff's law. Reason : It is based on conservation of energy.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
The sum of all the currents directed towards a point in circuit is equal to the sum of all the currents directed away from that point. It is based on conservation of electrical energy.
