Physics - Current Electricity Question with Solution | TestHub

Resistors of resistance$20\mathrm{\Omega }$and$30\mathrm{\Omega }$are joined in series with a battery of emf$3\mathrm{V}$. It is desired to measure current and voltage across the$20\mathrm{\Omega }$resistor with the help of an ammeter and a voltmeter. Identify the correct arrangement of ammeter ($A$) and voltmeter ($V$) out of four possible arrangements shown in the figure given below.
