Physics for IGCSE & O level - Electricity (Section 5 - No. 1)
What is the relationship between current and the number of parallel paths in a circuit?
As the number of paths increases, the current decreases
As the number of paths increases, the current increases
The number of paths has no effect on the current
The current is independent of the number of paths if voltage is fixed
解释
More parallel paths offer less total resistance for a set voltage, and therefore allow for more total current.
