Working Principle of AC Generator
The working of an AC generator is based on the principle of the law of electromagnetic induction which states that
A current-carrying conductor when placed in a uniform magnetic field experiences a force due to the interaction between the conductor and the magnetic field known as the EMF (Electromotive Force).
Working Principle: As we observe from the diagram of the AC generator, the generator consists of an armature coil that is placed between two poles as shown. The armature coil is made to rotate in the magnetic field of the poles. Due to the rotation of the armature in the magnetic field, the flux associated with the coil changes. Based on the principle of electromagnetic induction, “a changing flux of the conductor in a uniform magnetic field induces current in the conductor.”
This results in the generation of electric current which is measured by the galvanometer. On careful observation, we see that the sign of current changes from positive to negative in each rotation which shows that the current generated in the AC generator is alternating current.
Applications of AC Generator
AC generator is an important tool used in the electronics field to study different concepts therefore, it becomes necessary to study what is an AC generator. In this article, we will study the AC generator and learn how it is useful in our daily lives. We will try to study the applications of AC generators through some real-life examples. Later, we will study the advantages and disadvantages of using an AC generator. In the end, we will discuss some potential developments in AC generators and how can impact future trends.
