"The sum of emf's and potential differences around a closed loop equals zero" is a consequence of
Options
- AOhm's law.
- BConservation of charge.
- CConservation of momentum.
- DConservation of energy.
Correct answer
D. Conservation of energy.
Step-by-step solution
Kirchhoff's voltage law states that the sum of all voltages around any closed loop in a circuit must equal zero. This is a consequence conservation of energy.
