What is the purpose of a fuse in an electrical circuit?
To prevent power supply ripple from damaging a component
To remove power in case of an overload✓پاسخ درست
To limit current and prevent shocks
All these choices are correct
توضیح
A fuse contains a conductor that melts and opens the circuit when current exceeds its rating, cutting power before wiring or equipment overheats. It protects the circuit against overload and short circuits, not people against shock, which is the job of a ground-fault device.
