VLOOKUP is a function in Excel used to search for a value in a table and return a corresponding value from a specified column.

• VLOOKUP stands for 'Vertical Lookup'.

• It is commonly used in Excel to search for a value in the leftmost column of a table and return a value in the same row from a specified column.

• The syntax for VLOOKUP is =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup]).

• Example: =VLOOKUP(A2, B2:D10, 3, FALSE) will search for the value in cell A2 in ...read more

The type of current used in instruments, electronics, and maintenance is typically alternating current (AC) or direct current (DC).

• Instruments, such as oscilloscopes and multimeters, often use AC or DC current depending on the application.

• Electronics circuits can be designed to work with either AC or DC current, with DC being more common for low voltage applications.

• Maintenance tasks may involve working with both AC and DC current, such as testing electrical systems in buildi...read more

The flow of complete PCB design involves schematic design, component placement, routing, design verification, and manufacturing.

• Schematic design: Create a schematic diagram of the circuit layout.

• Component placement: Position components on the PCB layout.

• Routing: Connect the components using traces on the PCB.

• Design verification: Check for errors and ensure functionality.

• Manufacturing: Prepare the design for production.

A transistor is a semiconductor device used to amplify or switch electronic signals.

• Transistors are fundamental building blocks of modern electronic devices.

• They can amplify electrical signals, control the flow of current, and act as switches.

• Common types of transistors include bipolar junction transistors (BJTs) and field-effect transistors (FETs).

5's Methodology is a systematic approach to workplace organization and standardization.

• 5S stands for Sort, Set in order, Shine, Standardize, Sustain

• It aims to improve efficiency, safety, and quality by organizing the workplace

• Example: Sorting out unnecessary items, arranging tools in a designated place, cleaning workstations regularly

PCB assembly in speedometer involves soldering electronic components onto a printed circuit board to ensure accurate readings.

• Ensure proper placement of components on the PCB

• Use soldering techniques to securely attach components

• Test the functionality of the speedometer after assembly

• Follow manufacturer's guidelines for assembly process

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, called the primary and secondary, wrapped around a magnetic core.

• When an AC current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.

• Transformers are used...read more

PLC stands for Programmable Logic Controller, used to automate industrial processes.

• PLC is a digital computer used to control machines and processes in manufacturing plants.

• It uses a programmable memory to store instructions and execute them in real-time.

• PLC systems are used in various industries such as automotive, food and beverage, and pharmaceuticals.

• They can be programmed using ladder logic, function block diagrams, or structured text.

• Examples of PLC systems include Siem...read more

A resistor is an electronic component that resists the flow of electrical current.

• Resistors are used to control the amount of current flowing in a circuit.

• They are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.

• Resistors dissipate energy in the form of heat when current flows through them.

• Common types of resistors include carbon film, metal film, and wirewound resistors.
