2.  Circuit Board Troubleshooting Techniques A)       Confirm the real problem in the circuit or the problem due to the error in the circuit  B)       consider a visual inspection first in the circuit C)       Select the troubleshooting tools D)       power the circuit E)       check the power supply block or points F)        check the individual components G)      check the main controller H)      check the loads on each component by the metered power supply 3)       What is the soldering bit temperature? Soldering temperature range of 300 to 400 °C 4)       What is a DC chopper? A chopper is  a device that converts fixed DC input to a variable DC output voltage directly . Essentially, a...

Types of Electronic component Active components In the electronic circuit, those components that require an external power source, to  control or modify electrical signals are called Active Components. Active components can Inject power into a circuit and are capable of electrically controlling and amplifying the flow of electrical current.             Examples – Diode, Transistor, SCR ( silicon-controlled rectifiers),  Generator, Alternator, Integrated circuit, Vacuum tube, LED, Photodiode, Op Amp, Seven Segment Display & Battery.   Passive components Passive components influence (প্রভাব) the flow of power , but do not require an external power source to function, is called Passive components. Examples - are resistors, inductors, capacitors, Transformers, Switches, Voltmeters, and Ammeters, LDR, thermistors, and Variable resistors. What is Electronic? Or  What do you understand from the word electronics? ...
