A student is provided with a variable voltage source V , a test resistor $\mathrm{R}_{\mathrm{r}}=10 \Omega$, two identical galvanometers $\mathrm{G}_1$ and $\mathrm{G}_2$ and two additional resistors, $\mathrm{R}_1=10 \mathrm{M} \Omega$ and $\mathrm{R}_2=0.001 \Omega$. For conducting an experiment to verify ohms law, the most suitable circuit is:
Options
A
B
C
D
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
To convert galvanometer into ammeter low resistances should be added into parallel & for voltmeter conversion, a very high resistance should be added in series.
