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 will produce some deflection. However, in case of ammeter (Ampere meter), most of this small current will flow through the shunt. Consequently the deflection of the ammeter will be practically nil.

  1. because volt meter is connected in series no current flow across v meter and circuit is not completed and a meter not show<br /> any deflection

  2. What happened if the ammeter connected before voltmeter. Does it show very high deflection on ammeter. Please explain, thanks in advance.

  3. Respected Electrical Technology,<br />plz add some introduction and strong interview questions on Transistor on monday, there is my interview at a multi-nationnal electronics company. Regards. my e.mail is hassanullah@hotmail.com, plz inform me through e.mail.<br /><br />
