Technician Supervisor Interview Questions and Answers

Basic knowledge of components is necessary for effective repair of electronics instruments.

• Understanding the function of each component helps in identifying faulty parts.

• Knowledge of components helps in selecting the right tools and techniques for repair.

• Components may need to be replaced or repaired, and knowledge of their specifications is important.

• Examples of components include resistors, capacitors, transistors, and diodes.

AC stands for Alternating Current and DC stands for Direct Current. AC changes direction periodically while DC flows in one direction.

• AC is used in household appliances and power grids while DC is used in batteries and electronic devices.

• AC voltage can be easily changed using a transformer while DC voltage cannot be changed easily.

• AC is more dangerous than DC because it can cause muscle contractions and heart fibrillation.

• DC is more efficient than AC for long-distance power t...read more

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

• Resistors: used to limit current flow

• Capacitors: used to store and release electrical energy

• Inductors: used to store energy in a magnetic field

• Diodes: used to allow current flow in one direction

• Transistors: used to amplify or switch electronic signals

• Integrated circuits: contain multiple components on a single chip

Capacitors can be placed in series or parallel depending on the desired capacitance and voltage rating.

• In series, the capacitance decreases while the voltage rating increases.

• In parallel, the capacitance increases while the voltage rating stays the same.

• When placing capacitors in series, the total capacitance is calculated as 1/Ctotal = 1/C1 + 1/C2 + ...

• When placing capacitors in parallel, the total capacitance is calculated as Ctotal = C1 + C2 + ...
