- Q2. How transformer works
- Ans.
Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
Transformers have two coils of wire, known as the primary and secondary coils.
When an alternating current flows through the primary coil, it creates a changing magnetic field.
This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy between the coils.
The r...
- Q3. Types of transformers
- Ans.
Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformers.
Step-up transformer increases voltage output
Step-down transformer decreases voltage output
Isolation transformer provides electrical isolation between primary and secondary windings
Autotransformer has a single winding with multiple taps for different voltage levels
Instrument transformers are used for measuring curre
- Q4. What is the work of red wires
- Ans.
Red wires are typically used for power connections in electrical circuits.
