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 / 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
