Why does the transformer convert the voltage?

A transformer converts voltage to increase or decrease electrical potential depending on the needs of the electrical system or device. It achieves this by using electromagnetic induction to transfer energy between two or more spools of wire. The main function of a transformer is to adjust voltage levels while maintaining the same frequency and allowing efficient transmission of energy over distances or adaptation to different electrical needs.

What does the transformer convert?

The transformer converts electrical energy from one voltage level to another using the principle of electromagnetic induction. This process involves transferring energy between the primary and secondary coils via a magnetic field created by alternating current. The voltage is adjusted based on the turns ratio between the primary and secondary windings, which determines whether the output voltage is higher or lower than the input voltage.

A transformer needs alternating current (AC) because alternating current creates a constantly changing magnetic field necessary for electromagnetic induction. This changing magnetic field induces a voltage in the secondary coil based on the principles of Faraday’s law. Direct current (DC) does not create a varying magnetic field, making it unsuitable for transformers, because a constant magnetic field cannot induce voltage in the secondary winding.

Why does a transformer need alternating current?

In short, a transformer works by transferring electrical energy between its primary and secondary windings via a magnetic field. When alternating current flows through the primary coil, it generates a fluctuating magnetic field in the core, which then induces a voltage in the secondary coil. The voltage level in the secondary coil is determined by the ratio of the number of turns in the primary and secondary windings, allowing the transformer to increase or decrease the voltage.

The voltage is transformed in a transformer according to the turns ratio between the primary and secondary coils. The voltage ratio is directly proportional to the transformation ratio; if the secondary coil has more turns than the primary, the voltage is increased (step-up transformer), and if it has fewer turns, the voltage is decreased (step-down transformer). This transformation process allows the voltage to be adjusted as needed for different applications.
