Question

ideal resistance for ammeter and voltmeter

Answer 1

HEYA !! HERE'S YOUR ANSWER. ..

●Ideal Voltmeter:

>>>Since voltmeter is connected in parallel with the element whose voltage is going to be measured,

for an ideal voltmeter NO current should flow through it, all current should pass through resister R, so that its(R's) voltage(resistance*current) can be accurately measured by voltmeter.

For no flow of current through voltmeter, we need INFINITE Resistance.

●Ideal Ammeter:

>>Since Ammeter is connected in series with the element whose current is going to be measured.

For an ideal Ammeter No voltage should appear across it. All the voltage should be appear across resister so that its(R's) current(voltage/resistance) can be accurately measured.

For no appear of voltage accross Ammeter, we need ZERO Resistance.

HOPE IT HELPS ✌. ..

Answer 2

HEYAA!

Here's the answer..

The ideal ammeter has zero internal resistance and a ideal volt meter has infinite has internal resistance.
