Question

The reading of ammeter shown in figure is

• A. $6.56A$
• B. $3.28A$
• C. $2.18A$
• D. $1.09A$

Answer 1

Answer: (C)

The equivalent circuit of the given circuit will be reduced to as shown in figure.

Total resistance of the circuit
$=\frac{2\times 4}{2+4}+0.8=\frac{8}{6}+0.8$
$=\frac{12.8}{6}\Omega$
Total current in the circuit $=\frac{14}{\left(12.8/6\right)}=\frac{84}{12.8}A$
Reading of ammeter $=\frac{84}{12.8}\times \frac{2}{6}$
$=2.18A$
