Physics for IGCSE & O level - Electricity (Section 4 - No. 30)
What is the effect of adding more resistors in parallel on the total current supplied by the voltage source?
The total current decreases.
The total current increases.
The total current remains the same.
The total current becomes zero.
Explanation
Adding more parallel paths lowers total resistance, which increases the current (I=V/R) if voltage stays the same.
