The circuit can be reduced as follows <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-nfzikafdtp9s.png" /> Reading of ammeter =I =(300/R / 3)=(900/R) As. R=1500 Ω , I=(3/5 )A

Q. Five identical resistors each of resistance $R = 1500 Ω$ are connected to a $300 V$ battery as shown in the circuit. The reading of the ideal ammeter $A$ is

$\frac{1}{5} A$

$\frac{3}{5} A$

$\frac{2}{5} A$

$\frac{4}{5} A$

The circuit can be reduced as follows

Reading of ammeter $= I$
$= \frac{300}{R /3} = \frac{900}{R}$
As. $R = 1500 Ω, I = \frac{3}{5} A$
