Exicom Interview Questions and Answers

Transistors are semiconductor devices used to amplify or switch electronic signals and electrical power.

• Transistors are the building blocks of modern electronic devices.

• They can function as amplifiers, increasing signal strength.

• Transistors can also act as switches, controlling the flow of electricity.

• Common types include Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs).

• Transistors are found...read more

A diode is a semiconductor device that allows current to flow in one direction while blocking it in the opposite direction.

• Diodes are used in rectifiers to convert AC to DC.

• Zener diodes regulate voltage in circuits.

• Light Emitting Diodes (LEDs) emit light when current flows through them.

• Schottky diodes have a low forward voltage drop and fast switching speed.

A 100Ah battery has a higher capacity than a 75Ah battery, thus it will last longer under the same load conditions.

• Battery capacity is measured in ampere-hours (Ah), indicating how much current a battery can supply over a specific time.

• A 100Ah battery can theoretically provide 100 amps for 1 hour, while a 75Ah battery can provide 75 amps for the same duration.

• If both batteries are used to power the same device dra...read more

Oscillator generates an AC signal of a specific frequency. Types include RC, LC, crystal, and relaxation oscillators.

• An oscillator is an electronic circuit that generates a periodic AC signal.

• RC oscillator uses a resistor and capacitor to control the frequency.

• LC oscillator uses an inductor and capacitor to control the frequency.

• Crystal oscillator uses a quartz crystal to generate a precise frequency.

• Relaxation os...read more
