Question

Transformer is a device used for

• A. Changing the electrical energy into mechanical energy
• B. Changing the mechanical energy into electrical energy
• C. Changing the voltage from one value to another without change in frequency
• D. Changing the frequency from one value to another without change in voltage

Hint:

Remember the energy conversions for key electrical devices:
• Motor: Electrical \(\rightarrow\) Mechanical
• Generator: Mechanical \(\rightarrow\) Electrical
• Transformer: Electrical \(\rightarrow\) Electrical (at different voltage/current levels) This helps differentiate them easily.
