Question

Four identical resistors each of R=4 are joined in a circuit......Find the rating of ammeter if cell B has e.m.f of 2 volt
The Answer is 3/8 A
I want the explanation of this came with correct redrawn diagram otherwise i will have to report
Please tell the answer

Answer 1

Answer:

⭐ SOLUTION ⭐

➡ If we redraw the diagram three resistor will be parallel and one resistor is in the series.

✏ So,

✳ Rep = 4/3R

✳ Res = 4/R

✳ Re = 4/R

✳ Re = Rep + Res

✳ Re = 4/3+4

✳ Re = 16/3

➡ Now, we know the formula

⭐ I = V/R ⭐

✏ I = 2×3/16

✏ I = 3/8 ✔
