questions in physics help me
1 ) How is the potential difference across a resistor measured ?
2) What are resistances of ideal voltmeter and Ammeter ?
3)what is the advantage of difital Multometer to use as voltmeter ?
my answer :
1) measured in peralled .
2 ) The internal resistance of an ideal voltmeter is infinity ohms. The internal resistance of an ideal ammeter is zero ohms.
3 )The digital readout gives you a single number instead of a dial pointing to several numbers on multiple scales
I want your help ,
