Question

Four resistor of $4\Omega$ each are connected to a 2 V battery as shown in the figure .The reading of the ammeter in the circuit is

• A. $\left(\frac{1}{8}\right)A$
• B. $\left(\frac{3}{8}\right)A$
• C. $\left(\frac{1}{2}\right)A$
• D. $2A$

Answer 1

The correct option is B $\left(\frac{3}{8}\right)A$

$R_{eq}=\frac{4}{3}+4$

$=\frac{16}{3}\Omega$

$i=\frac{2}{16}\times 3=\frac{3}{8}A$

$\therefore ammeterreadingis\frac{3}{8}A$

Hence,

option $\left(B\right)$ is correct answer.
