Question

The reading of ammeter shown in figure is

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

Answer 1

Answer: (C)

2.18 A

Answer 2

: 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,

$= \frac{14}{(12.8/6)} = \frac{84}{12.8}A$

Reading of ammeter,

$= \frac{84}{12.8} \times \frac{2}{6} = 2.18A$
