Question

1. An ideal ammeter should have a resistance of______________ while an ideal voltmeter should have a resistance of _________________.
2. Explain why these are desirable attributes for the respective measuring instruments.

Answer 1

Answer:

Explanation:

1. An ideal ammeter has very small or almost zero resistance. As the resistance is small the maximum current can pass through the ammeter which it can read it.

2. An ideal voltmeter has very large or infinite resistance. As the resistance is very large so the maximum voltage drops across the resistor and gives the accurate reading.
