Unicorn DenMart Interview Questions, Process, and Tips

Power can be converted from AC to DC using a rectifier circuit.

• Use a rectifier circuit to convert AC to DC

• Rectifier circuit consists of diodes which allow current to flow in one direction only

• Examples of rectifier circuits include half-wave, full-wave, and bridge rectifiers

Basic components of electronics include resistors, capacitors, inductors, diodes, transistors, and integrated circuits.

• Resistors: Control the flow of electric current in a circuit.

• Capacitors: Store and release electrical energy.

• Inductors: Store energy in a magnetic field.

• Diodes: Allow current to flow in one direction only.

• Transistors: Amplify or switch electronic signals.

• Integrated Circuits: Contain multiple components

The latest system configuration for a PC includes high-end processors, ample RAM, fast SSD storage, and advanced graphics cards.

• High-end processors such as Intel Core i9 or AMD Ryzen 9 series

• Ample RAM capacity of 16GB or more for multitasking and gaming

• Fast SSD storage for quick boot times and application loading

• Advanced graphics cards like NVIDIA RTX 30 series or AMD Radeon RX 6000 series

A diode is a semiconductor device that allows current to flow in one direction only. AC can be converted to DC using rectifiers. Microprocessors process data using logic circuits. Transistors amplify or switch electronic signals. AC motors run on alternating current while DC motors run on direct current. Power supplies can work with both AC and DC inputs. Resistance is the opposition to the flow of electric current. Re...read more

Relays are electrically operated switches used to control high power devices with low power signals.

• Relays consist of a coil, an armature, and one or more contacts.

• When current flows through the coil, it creates a magnetic field that attracts the armature, closing the contacts.

• Relays are commonly used in control circuits to switch high power devices such as motors, lights, and heaters.

• They can be used to isolate contro...read more
