Is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. Principle of operation It works by converting electrical energy into mechanical energy (motion). The mechanical energy compresses air and converts the motion into sound energy. When an electric current is sent through a coil of wire, it induces a magnetic field.…

Classification of DC Machines    DC motors Converts DC power to mechanical power DC generators Convert mechanical power to DC electrical power. Working principle of DC Machines When electric current flow through a coil within a magnetic field, the interaction of magnetic from electromagnet and that created by current flowing in the coil generates a…

Interrupts are the signals generated by the external devices to request the microprocessor to perform a task. There are 5 interrupt signals, i.e. TRAP, RST 7.5, RST 6.5, RST 5.5, and INTR. Interrupt are classified into following groups based on their parameter − Note − NTA is not an interrupt, it is used by the microprocessor for…
