Flex Interview Questions, Process, and Tips

Active components are capable of providing power gain while passive components cannot.

• Active components require an external source of power to operate while passive components do not.

• Examples of active components include transistors, operational amplifiers, and integrated circuits.

• Examples of passive components include resistors, capacitors, and inductors.

• Active components can amplify signals while passive components c...read more

The unit of resistance is Ohm and the unit of capacitor is Farad.

• Resistance is measured in Ohms (Ω)

• Capacitance is measured in Farads (F)

• Ohm's law relates resistance, voltage, and current

• Capacitance is the ability of a capacitor to store electric charge

A microcontroller is a small computer on a single integrated circuit that contains a processor core, memory, and programmable input/output peripherals.

• Microcontrollers are used in various applications such as embedded systems, robotics, and consumer electronics.

• They are designed to execute specific tasks and are often used in devices that require real-time control.

• The 8051 microcontroller is a popular 8-bit microcontro...read more

A zener diode is a type of diode that allows current to flow in the reverse direction when a certain voltage threshold is reached.

• Zener diodes are commonly used in voltage regulation circuits.

• They are designed to operate in the breakdown region, where a small change in voltage results in a large change in current.

• Zener diodes are often used to protect sensitive electronic components from voltage spikes.

• They can also be...read more

Diodes are electronic components that allow current to flow in one direction only.

• Diodes have two terminals: an anode and a cathode.

• When a voltage is applied to the anode, current flows through the diode.

• If the voltage is reversed, the diode blocks the current.

• Diodes are commonly used in rectifiers, voltage regulators, and signal limiters.
