Resistance across X Y=(2/3) Ω <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/2839091a20005758426e0d52d6d45218-.png" /> Total resistance =2+(2/3)=(8/3) Ω Current through ammeter =(2/8 / 3)=(6/8)=(3/4) A

Q. The reading of the ammeter as per figure shown is

$\frac{1}{8} A$

$\frac{3}{4} A$

$\frac{1}{2} A$

$2 A$

Resistance across $X Y = \frac{2}{3} Ω$

Total resistance $= 2 + \frac{2}{3} = \frac{8}{3} Ω$
Current through ammeter $= \frac{2}{8/3} = \frac{6}{8} = \frac{3}{4} A$

Q. The reading of the ammeter as per figure shown is

81​A

43​A

21​A

2A

Resistance across XY=32​Ω Total resistance =2+32​=38​Ω Current through ammeter =8/32​=86​=43​A

$\frac{1}{8} A$

$\frac{3}{4} A$

$\frac{1}{2} A$

$2 A$

Resistance across $X Y = \frac{2}{3} Ω$

Total resistance $= 2 + \frac{2}{3} = \frac{8}{3} Ω$
Current through ammeter $= \frac{2}{8/3} = \frac{6}{8} = \frac{3}{4} A$
