Question 182: Current Electricity

Question

A student is provided with a variable voltage source $$\mathrm{V}$$, 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 ohm's law, the most suitable circuit is:

Accepted Answer

For voltage measurement across $R_T$
Voltmeter should have very high resistance
$\Rightarrow R_1$ should be in series with $G_1$ and Ammeter should be having very less resistance
$\Rightarrow R_2$ should be in parallel with $G_2$
