Electric transformers are static electrical machines that transform electric power from one circuit to the other without changing the frequency. An electrical transformer can increase or decrease the voltage with a corresponding increase or decrease in electric current. The working principle of an electric transformer is based on the basic principles of electromagnetic induction as well as mutual induction.

Applications of Electric Transformers
Electric transformers play an important role in our daily lives as they either decrease or increase the electrical current to meet our daily needs in our use of electrical appliances. Some of the uses of electric transformers include controlling the flow of voltages during charging as unregulated voltage flow may result in electrical surges. And this may result in damage to the appliances which are being charged.
Benefits of Electric Transformers
Electric transformers are cost efficient as the traditional transformer provides a cheap and very reliable method for voltage transmission and isolation. The sense that these transformers come in various types enables them to be used in various different areas, for example current transformers are used to step down currents for the measurement instruments. Transformers can be connected in a reverse manner in the sense that the same transformer can be wired to be a step up transformer or a step down transformer depending on how it is installed. To accommodate multiple input voltages, some electric transformers are fitted with multiple taps on the primary winding.
