In the circuit diagram shown, the two resistance wires A and B are of same 2 points
area of cross section and same material but A is longer than B. Which
ammeter A1 and A2 will indicate higher reading of current? Give reason.

ammeter A2 because length is inversely proportional to volt and
volt is directly proportional to current
