Current Electricity

Solution:

The equivalent circuit of the given circuit will be reduced to as shown in figure.
image
Total resistance of the circuit $=\frac{2 \times 4}{2+4}+0.8=2.13\, \Omega$
Total current in the circuit $=\frac{14}{2.13}=6.57\, A$
Reading of $=6.57\, A \times \frac{2}{6}=2.18\, A$
