Exicom Interview Questions, Process, and Tips for Experienced

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.

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 in e...read more

Cell grading is the process of evaluating and categorizing cells based on their characteristics and quality.

• Cell grading is commonly used in fields such as biology, medicine, and manufacturing.

• It involves assessing factors like cell size, shape, structure, and function.

• Grading cells can help determine their health, viability, and potential uses.

• For example, in medical diagnostics, cell grading may be used to classify c

Lithium ion batteries are rechargeable batteries commonly used in electronic devices.

• Lithium ions move from the negative electrode to the positive electrode during discharge

• They are lightweight and have a high energy density

• Commonly used in smartphones, laptops, and electric vehicles
