– Its operation relies on melting due to excessive heat.
– The heat generated is proportional to the square of the current and the resistance of the wire (H = I²Rt).
– Magnetic effect of current is used in devices like motors, relays, and electromagnets.
– Optical property of current is not a standard term; effects like light emission (LEDs) are related to current flow but not the principle behind a fuse.
