About

You will be able to

  • Determine figure of merit and use galvanometers as meters
  • Measure low resistance, inductance and capacitance with bridges
  • Study series and parallel LCR resonance and find the Q factor
  • Measure magnetic field along the axis of a coil
  • Use the spectrometer and grating to find wavelengths

Who it is for

  • B.Sc students with Physics, Semester 3 (UP state universities, NEP 2020)
  • Students preparing for university semester exams and entrance tests such as IIT-JAM / CUET-PG (basic level)

What you need

  • Enrolled in B.Sc with Physics as a major subject
  • Practical file / lab record notebook
  • Scientific calculator and graph paper

Questions

Which syllabus does this course follow?

It follows the UP State Universities NEP 2020 common minimum syllabus for B.Sc. Where your own university's syllabus differs, the centre teaches your university's units and papers.

Are the experiments done in the centre?

The centre covers theory, observation tables, calculations and viva for each experiment; experiments needing college apparatus are done in your college lab.

Is spectrometer adjustment taught?

Yes, Schuster's method and levelling of the spectrometer are taught step by step because examiners check it.
