Answer:
Given V= 12V.
Total resistance =2+1= 3ohm.
Total current = 12/3 = 4A.
Current through 3ohm resistor = 4×6/9 = 4×2/3= 8/3 = 2.66A.
Therefore ammeter reading = 2.66A.
Explanation:
Current splits in parallel combination of resistors.
To find the current in each branch use the formula,
Total current× Resitance of the opposite branch/ total resistance of the two branch.
