I 've been said that the more internal resistance meter has, the better that meter is, is it right or wrong ? and why ?
Thanks !!!
 

Hi,
It depends on which type of meter you are talking about. An ideal current meter should have zero resistance to make the potential drop accross it zero volt and an ideal volt meter should have infinite resistance to make the current drawn by it to zero amps. In other words, introduction of a meter into the circuit should not affect the parameter it measures.

i think that right
for a meter to measure voltage u want more voltage to drop at ur load..so for this u must have low internal resistance...

for meter to measure current u need to have low load resistance to have more current at ur load...so for this internal resistance must be high.
 

I agree with Laktronics
 

Yeah, me too and thank you !!!
