Answer / muhammad jabir
connect both meter in series the one which show high reading
is volt meter other shows reading close to zero is ammeter

Answer / ashok mishra sddiet
connect both in series with the source as amitter having low resistance will show high reading and voltmetre having high resistance will show low or almost zero
| Is This Answer Correct ? | 1 Yes | 0 No |
Answer / d vittaleshwar
voltmeter is designed with high resistance and ammeter is designed with low resistance.with out giving supply to the meters also we can find which is ammeter and which is voltmeter.

Answer / karna
Voltmeter is connected in parallel and Ammeter is connected
in Series. Based on the we can identified which meter
| Is This Answer Correct ? | 1 Yes | 6 No |
Answer / raghavansa
The resistance of voltmeter is high and the ammeter is low.
So check the meter wires with multimeter and found
