Why voltmeter is not connected in seris & ammeter connected
in parallel ?
Answer Posted / qureshi majid
The voltmetre is used for measuring the electrical potential
difference between two points of a line,where as the
potential difference measured between two points of same
wire/line is zero.In short!the internal resistance of
voltmetre is generally high,so you cannot connect it in series.
The ammetre having minimum internal resistance,supports the
idea of connecting it in series,because you want to measure
the current of a wire and current is same in a circuit
connected in series.The net effect is that the setup of
equipment discussed above does not affect the circuit behaviour
