Assembler Interview Questions and Answers

A transistor is a three-pin electronic component with pins named Base, Emitter, and Collector.

• Transistors are used to amplify or switch electronic signals.

• The Base pin controls the flow of current between the Emitter and Collector pins.

• The Emitter is the source of electrons, while the Collector collects them.

• Transistors are commonly used in electronic devices such as computers, televisions, and radios.

Electronic components are devices that perform specific functions within an electronic circuit.

• Electronic components are used to control the flow of electric current or to amplify signals.

• They can be passive components like resistors, capacitors, and inductors, or active components like transistors and integrated circuits.

• Each component has a specific function, such as storing energy, filtering signals, or converting one form of energy to another.

• For example, a resistor limit...read more

Voltage is the potential difference between two points in an electrical circuit that drives the flow of electrons.

• Voltage is measured in volts (V).

• It represents the amount of energy carried by each unit of charge.

• Voltage can be compared to the pressure in a water pipe, where higher voltage means more potential energy for electrons to flow.

• Voltage is essential for the operation of electronic devices and electrical systems.

• Examples of voltage sources include batteries and power...read more

An ammeter measures electric current in a circuit.

• Ammeters are used to measure the flow of electric current in a circuit.

• They are connected in series with the circuit to measure the current passing through it.

• The unit of measurement for current is amperes (A).

• Ammeters have low resistance to avoid altering the circuit's current.

• For example, an ammeter can be used to measure the current flowing through a light bulb.
