Hi Chanchal,
Well, first of all, you can't get something for nothing. The work electricity can do is measured in watts. Light a bulb, run a microwave, a hair dryer, whatever. And watts are calculated using Ohms Law:
E (volts) times I (current) = P (power, in watts). So, for a given amount of power, if E goes up, I must go down.
Transformers pass current by the primary generating a magnetic fiel, which induces a current and voltage in the secondary. You can step up, down, or neither voltage.This is accomplished by having a different number of windings on the primary and secondary coils. If the number of turns on the coil in both primary and secondary coils is the same , the voltage and current on both sides will be the same, minus the loss incurred across the transformer. Commercial transformers are very efficient, upwards of 95%.
If the windings on the secondary are twice as many as on the primary, the voltage will double, the current will halve.
I hope it's clear.
All the best.

Hello Shubham,
The ideal options for a B.Sc physics graduate is M.Sc in:
1. Acoustics.
2. Applied electronics.
3. Astronomy.
4. Astrophysics.
5. Geophysics.
6. Medical physics.
7. Nuclear physics.
8. Vacuum sciences.
Once you complete your Master's degree, you can look forward to pursue either M.Phil in physics, M.Phil in applied mathematics, statistics or computing and mathematical sciences.
Further taking yourself into the research field with options like:
1. Ph.D physics.
2. Master of research in physics.
With a Master's degree in physics, you can get jobs with research institutions as technician or as instructor. It is also possible for you to get employed with the defense sector. With a doctorate, you can get jobs with automobile and other related industries.
MCA will help you, if you aim for a career in programming, database administration, networking, software development, etc.
