Detailed Solution
Download Solution PDF- An electric motor is an electrical machine that converts electrical energy into mechanical energy.
- Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.
- An electric generator (Dynamo) is mechanically identical to an electric motor, but operates in the reverse direction, converting mechanical energy into electrical energy.
- An uninterruptible power supply (UPS), also known as a battery backup, provides backup power when your regular power source fails, or voltage drops to an unacceptable level.
- A UPS allows for the safe, orderly shutdown of a computer and connected equipment.
- SMPS stands for switch-mode power supply. Its job is to convert wall-voltage AC power to lower voltage DC power.
- Most computer chips in modern computers require power generally of 1.2 - 3.3V, with some older devices requiring between 5 - 12V DC.
