The rotor in an induction motor is connected to AC or DC power.

In an induction motor, the rotor does not have any external electrical connection to power sources, such as AC or DC. Instead, the rotor operates based on the electromagnetic induction principle. This principle means that a rotating magnetic field created by the alternating current in the stator windings induces a current in the rotor, which then creates its own magnetic field. This interaction causes the rotor to turn.

The answer highlights that the rotor is not directly connected to any external power source, making the statement false. Induction motors are designed to work with an AC power supply for the stator, while the rotor relies on the effects of electromagnetic induction rather than an external power connection.
