Question

Study the following circuit and find out current in 12 ohm resistor and difference in the reading of A1 and A2 if any

Answer 1

which circuit do we have to see

Answer 2

Hey dear,
You didn't provide the diagram. I've added it in image attachment.

● Answer -
1) I = 0.25 A
2) Difference in the reading of A1 and A2 is zero.

● Answer -
Equivalent resistance of wire -
R = 24/(1+1) + 12
R = 24 ohm

Current flowing through wire -
I = V / R
I = 6 / 24
I = 0.25 A


Both ammeters A1 & A2 measure the current through same wire at different points.
Therefore reading in both the ammeters will be same.

Hope this helps you.
Keep asking.
