Basic Working principle of Motors, ups, Transformer

Question

Accepted Answer

Motors convert electrical energy to mechanical energy, transformers transfer electrical energy between circuits, and UPS provides backup power.

Motors operate on the principle of electromagnetic induction, converting electrical energy into mechanical energy.
Example: An electric motor in a fan spins blades to create airflow.
Transformers use electromagnetic induction to transfer electrical energy between circuits at different voltage levels.
Example: Step-up transformers increase voltage for efficient long-distance power transmission.
Uninterruptible Power Supplies (UPS) provide backup power by using batteries to supply electricity during outages.
Example: A UPS for a computer keeps it running during a power failure.
