- Q1. Functions of basic electronic componenents like R L C
- Ans.
R, L, and C are basic electronic components used in circuits for resistance, inductance, and capacitance respectively.
Resistors (R) limit current flow and reduce voltage
Inductors (L) store energy in a magnetic field and resist changes in current
Capacitors (C) store energy in an electric field and pass AC signals while blocking DC signals
These components are used in various circuits such as filters, oscillators, and amp

Interview Preparation Tips
Experience: Written round consists of Analytical Test and Verbal Ability Test. TCS has various criteria for skipping Analytical Test. If you are a geek ( in top five of a few stream like CSE/IT/ECE/EE/Mechanical ) then you will be allowed toskip the Analytical round. Also if you have at least 75% aggregate in 10th and 12th and a minimum percentage marks in college ( This is set by TCS and varies from college to college, May be 8.5 pointer or 7.90 or as desired by TCS ) then you can skip analytical round. TCS is continuously changing its placement process so prepare for the worst and do not pretend that you can skip the analytical round even if you are a geek.If you are taking only verbal part then you will get ten minutes time and within this time frame you need to write an email based on the given scenario.
