Two ammeters A and B both 0-10 A have internal resistance of 1 Ω and 0.5 Ω respectively. They are connected in parallel. If total current is 15 A, then
IA = IB = 7.5 A
IA = 5 A, IB = 10 A
IA = 10 A, IB = 5 A
IA = 9 A, IB = 6 A
Answer: Option
Explanation:

Currents divide in inverse proportion of resistances.
