True or False: The arc from a fuse blowing is extinguished by erosion of the fuse holder tube.

The statement is true because the design of a fuse includes a fuse holder tube that plays a critical role in interrupting the electrical circuit when a fuse blows. When the fuse element melts due to an overload or short circuit, it creates an arc due to the high current flowing through the circuit. This arc can continue to produce heat and sustain the electrical connection if not properly extinguished.

The fuse holder tube is made from materials that can withstand high temperatures, and it helps extinguish the arc by providing a controlled environment for the fuse wire to melt and create gases that cool and dissipate the energy of the arc. As the fuse element erodes from this rapid melting and the resulting gases expand within the confines of the tube, the arc is effectively extinguished, reducing the likelihood of further damage or fire in the circuit.

Other choices imply scenarios specific to voltage levels or contradictory statements about the functionality of the fuse holder tube, which does not take into account the fundamental operation of fuses across various voltage situations. The arc extinguishing process via erosion of the fuse holder tube is a crucial mechanism present universally in fuse designs.
