Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFGiven V = 12 V
Applying Ohms Law at 4 Ω resistor, we get:
12 = I × 4
I = 3 A
The circuit is redrawn as shown:
Using current division, we get:
\(I_1 =3\times \frac{R_1}{R_1+R_2}\)
\(I_1 =3\times \frac{8}{8+4}=2~A\)
So the ammeter will read 2 A.
