Station Operator Interview Questions and Answers

A capacitor is an electronic component that stores and releases electrical energy in a circuit.

• Capacitors store electrical energy and release it when needed.

• They are used to filter out noise and stabilize voltage levels in power supplies.

• Capacitors can also be used for timing circuits, coupling signals, and storing data.

• Examples of capacitor applications include smoothing power supply ripples, motor starting, and audio filtering.

A register in an electronic circuit is used to store and manipulate data temporarily.

• Registers are used to store data during processing in a computer or electronic device.

• They can hold binary data, such as numbers or instructions.

• Registers are often used for arithmetic and logical operations.

• They can also be used for data transfer between different parts of a circuit.

• Examples of registers include the program counter, accumulator, and memory address register.
