Ac Transformer
An AC transformer is a device that is used to transfer electrical energy from one circuit to another, through electromagnetic induction. It is typically used to increase or decrease the voltage of an alternating current (AC) power supply. AC transformers are made up of two coils of wire, which are wound around a magnetic core. The primary coil is connected to the power supply, while the secondary coil is connected to the load. As the current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil. The ratio of the number of turns in the primary and secondary coils determines the voltage transformation ratio. AC transformers are widely used in power distribution systems, electrical appliances, and electronic devices.

Q:
What is an AC transformer?A:
An AC transformer is an electrical device that is used to transfer electrical energy from one circuit to another circuit through electromagnetic induction.Q:
What is the difference between step-up and step-down transformers?A:
Step-up transformers increase the voltage of the input signal, while step-down transformers decrease the voltage of the input signal.Q:
What is the efficiency of an AC transformer?A:
The efficiency of an AC transformer is determined by the ratio of output power to input power. Ideally, the efficiency should be 100%, but in reality, there are some losses due to factors such as resistance and hysteresis.Q:
What are some common applications of AC transformers?A:
AC transformers are used in a variety of applications, including power distribution, electric motors, and electronic devices such as audio amplifiers and computer power supplies.
