A Voltmeter, an ammeter (Ampere meter) and a battery cell are connected in series. It is observed that ammeter practically shows No Deflection. Why?

 A Voltmeter, an ammeter (Ampere meter) and  a battery cell are connected in series. It is observed that ammeter practically shows No Deflection. Why? Due to the large resistance of the voltmeter, the circuit resistance becomes very high. As a result, very small current will flow in the circuit. this small current f on passing through the coil of voltmeter …
