MCQ
A student is provided with a variable voltage source $V$, a test resistor $R_T=10\,\Omega$, two identical galvanometers $G_1$ and $G_2$ and two additional resistors, $R _1=10\,M\,\Omega$ and $R _2=0.001\,\Omega$. For conducting an experiment to verify ohms law, the most suitable circuit is:
  • A

  • B


  • D

Answer

Correct option: C.

c
To convert galvanometer into ammeter low resistances should be added into parallel and for voltmeter conversion, a very high resistance should be added in series.
