The sum of potential changes around a closed loop is zero. This follows from conservation of what?
ALinear momentum
BMagnetic flux
CRest mass
DTotal energy
Answer & Solution
Correct answer: D. Total energy
Around a closed loop the potential changes sum to zero because the electrostatic field is conservative, so energy is conserved.
