Question:- The reading of the ammeter in the circuit below is 
Solution: - 
 
From circuit diagram it can be observed that the ammeter is connected in parallel to the battery. 
Potential drop will be same across the ammeter and the resistance connected in series with the ammeter. 
Resistance = 2 + 2 = 4 ohms 
Thus, the current reading in the ammeter is, 
I = V/R
I = 20/4 = 5 A 
Correct option is (1)  5 A
