alleryA flow of negative charges one way has the same circuit effect as a flow of positive charges in which direction?
AThe same direction
BAcross the wire only
CThe opposite direction
DNo direction at all
Answer & Solution
Correct answer: C. The opposite direction
1. A flow of positive charges gives the same current as an equal flow of negative charges in the opposite direction.
2. The same direction would add, not match, the effect.
3. So the opposite direction is correct.
