How is resistance described as a property of a wire or circuit component?
AHow much charge a component can store before overheating
BHow much a component opposes the flow of charge through it
CThe total voltage a component can generate on its own
DThe number of electrons a component contains at rest
Answer & Solution
Correct answer: B. How much a component opposes the flow of charge through it
1. Resistance is introduced as arising from obstacles that slow the flow of current, such as impurities or collisions.
2. It is explicitly described as how much a component opposes the flow of charge through it.
3. Storing charge and generating voltage are properties of capacitors and batteries, not resistance.
