Short circuit:
The two poles of the power supply (or the live wire and the neutral/ground wire) are directly connected, the resistance approaches 0, and the current surges instantly (similar to "wires directly touching each other"), causing a sharp increase in current, overheating, and fire, and damaging the equipment.
Open circuit:
A certain part of the circuit is disconnected (such as a wire breakage, poor contact of the switch), and the current cannot flow, similar to "a blocked water pipe".
Leakage current:
Current leaks through an unexpected path (such as the live wire touching the casing, damaged insulation of the wire). It flows to the ground or other conductors. The current "leaks away" and may cause electric shock.
Overload:
The total power of the circuit exceeds the designed carrying capacity (such as turning on multiple high-power appliances simultaneously), and the current remains high for a long time. The current keeps being too high, the wire heats up, and the switch trips.
