PCB stands for Printed Circuit Board, a board made of non-conductive material with conductive tracks for electronic components.
PCB is used to mechanically support and electrically connect electronic components using conductive pathways.
It is made of non-conductive material like fiberglass, with copper tracks to connect components.
PCBs can be single-sided, double-sided, or multi-layered depending on the complexity of th...
Active components require a power source to operate, while passive components do not.
Active components require an external power source to function, such as transistors and integrated circuits.
Passive components do not require an external power source, such as resistors and capacitors.
Active components can control the flow of electricity, while passive components simply store or dissipate energy.
Examples of active comp...
Resistance is the opposition to the flow of current in a circuit, while a capacitor stores and releases electrical energy.
Resistance limits the flow of current, while a capacitor stores and releases charge.
Resistance is measured in ohms, while capacitance is measured in farads.
Examples of resistors include carbon film resistors, while examples of capacitors include ceramic capacitors.
Resistance dissipates energy in the...
SMT stands for Surface Mount Technology, a method of electronic component assembly where components are mounted directly onto the surface of a printed circuit board (PCB).
SMT components are smaller and lighter than through-hole components, allowing for higher component density on PCBs.
SMT components are typically mounted using solder paste and reflow soldering techniques.
SMT technology allows for automated assembly pro...

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) signal.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding receives electrical energy from a power source, while t...
Current is the flow of electric charge through a conductor.
Current is measured in amperes (A).
It is caused by the movement of electrons or ions.
Current can be either direct current (DC) or alternating current (AC).
DC flows in one direction, while AC periodically changes direction.
Examples of current include the flow of electricity in a circuit or the movement of ions in an electrolyte solution.
L&T Construction interview questions for designations
Speed control methods of induction motor include voltage control, frequency control, and rotor resistance control.
Voltage control: By varying the voltage supplied to the motor, the speed can be controlled.
Frequency control: By changing the frequency of the power supply to the motor, the speed can be adjusted.
Rotor resistance control: By inserting external resistance in the rotor circuit, the speed can be regulated.
Vari...
