Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit...read more

An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.

• Induction motors are commonly used in various industrial applications due to their simplicity and reliability.

• They do not require any brushes or commutators for operation.

• The speed of an induction motor is determined by the frequency of the AC power supply and the number of poles in the motor.

• Examples of induction...read more
