A voltmeter must not steal current from the circuit. Its own resistance is therefore:
AVery warm
BVery short
CVery large
DVery small
Answer & Solution
Correct answer: C. Very large
1. It sits across the component in parallel.
2. A low resistance would divert the current.
3. So its resistance is very large.
