Physics for IGCSE & O level - Electricity (Section 3 - No. 43)
In a parallel circuit, if one branch opens (breaks the circuit), what happens to the other branches?
The current in the other branches decreases.
The current in the other branches increases.
The current in the other branches remains the same.
The other branches also open.
Explanation
In a parallel circuit, other branches continue to function, assuming no overload.
