An induced voltage always reacts how to the applied voltage?

The concept of induced voltage is rooted in Faraday's Law of Electromagnetic Induction, which states that a change in the magnetic field within a circuit induces an electromotive force (EMF) in that circuit. This induced voltage inherently behaves according to Lenz's Law, which asserts that the direction of induced voltage will be such that it opposes the change in the magnetic field that produced it.

When an external voltage is applied to a circuit, it creates a magnetic field. If the magnetic field changes, then the induced voltage reacts in a way that acts against the applied voltage. This opposition is crucial for maintaining stability in electrical systems; it helps to counteract fluctuations and resist any rapid changes that might otherwise lead to circuit damage or inefficiencies.

Understanding this relationship is vital for linemen, as it impacts how electrical systems respond to varying loads and other dynamic conditions in the environment, ensuring safety and reliability in power transmission systems.
