Question
The sum of the voltages over any closed loop is equal to __________
Solution
The sum of the voltages over any closed loop is equal to the sum of the emf sources present in that loop. This is known as Kirchhoff's Voltage Law. It states that the algebraic sum of all the potential differences (voltages) around any closed loop or mesh in a network is always equal to zero. This is because a circuit loop is a closed conducting path, so no energy is lost.
