A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate.

A cord of readily combustible material that is lighted at one end to carry a flame along its length to detonate an explosive at the other end.

An electrical device, such as a semiconductor or electron tube, through which flow of current is generally restricted to one direction. Diodes are often used in or as rectifiers.

Often fuze A mechanical or electrical mechanism used to detonate an explosive charge or device such as a bomb or grenade

(electronics) An electronic device that allows current to flow in one direction only; used chiefly as a rectifier.

A safety device that protects an electric circuit from excessive current, consisting of or containing a metal element that melts when current exceeds a specific amperage, thereby opening the circuit.

A thermionic tube having two electrodes; used as a rectifier

To equip with a mechanical or electrical fuse.

A semiconductor that consists of a p-n junction

To join (different pieces or elements) together physically, as by melting or heating

To blend or combine together

To liquefy or reduce to a plastic state by heating; melt.

To become physically joined together, as by melting.

To be combined or blended together

To become liquefied from heat.

A cord that, when lit, conveys the fire to some explosive device.

The mechanism that ignites the charge in an explosive device; a detonator.

(figurative) A tendency to lose one's temper.

A friction match for smokers' use, having a bulbous head which when ignited is not easily blown out even in a gale of wind.

A kind of match made of paper impregnated with niter and having the usual igniting tip.

(electrical engineering) A device to prevent excessive overcurrent from overload or short circuit in an electrical circuit, containing a component that melts and interrupts the current when too high a load is passed through it.

To furnish with or install a fuse to (an explosive device) Usage notes]] for noun above.

(transitive) To liquify by heat; melt.

(transitive) To melt together; to blend; to mix indistinguishably.

(intransitive) To melt together.

To furnish with or install a fuse to protect a circuit against overcurrent.

To have been protected against overcurrent by its fuse melting away, creating a gap in the wire, thus stopping the circuit from operating.

(organic chemistry) To form a bicyclic compound from two similar or different types of ring such that two or more atoms are shared between the resulting rings

To liquefy by heat; to render fluid; to dissolve; to melt.

To unite or blend, as if melted together.

To be reduced from a solid to a fluid state by heat; to be melted; to melt.

To be blended, as if melted together.

A tube or casing filled with combustible matter, by means of which a charge of powder is ignited, as in blasting; - called also fuzee. See Fuze.

A mechanism in a bomb, torpedo, rocket, or artillery shell, usually having an easily detonated explosive charge and activated by the shock of impact, which detonates the main explosive charge. Some fuses may have timing mechanisms, delaying the explosion for a short time, or up to several days after impact. Fuses activated by other mechanisms more sophisticated than impact, such as proximity or heat, are used in modern weapons such as antiaircraft or antimissile missiles.

A wire, bar, or strip of fusible metal inserted for safety in an electric circuit. When the current increases beyond a certain safe strength, the metal melts, interrupting the circuit and thereby preventing possibility of damage. It serves the same function as a circuit breaker.

Electrical device that can interrupt the flow of electrical current when it is overloaded

Any igniter that is used to initiate the burning of a propellant

Mix together different elements;

Become plastic or fluid or liquefied from heat;

Equip with a fuse; provide with a fuse

Make liquid or plastic by heating;

A diode works by allowing current to flow through it in one direction, utilizing a p-n junction.

Diodes are used in rectification, protection against reverse polarity, and signal modulation.

A diode is a component that allows current to flow in only one direction.

A fuse works by melting when the current exceeds a certain level, thereby breaking the circuit.

When a fuse blows, it breaks the circuit to prevent damage from overcurrent.

A fuse is a device that protects circuits from excessive current by melting and breaking the circuit.

No, because a diode does not break the circuit under excessive current.

No, a fuse cannot regulate current flow direction; it only protects against overcurrent.

A rectifier uses diodes to convert AC to DC, whereas a diode is the component performing the conversion.

Key parameters include current rating and breaking capacity.

No, once a fuse has blown, it needs to be replaced.

Fuses are used in electrical and electronic circuits for overcurrent protection.

Key parameters include forward voltage drop and reverse breakdown voltage.

A fuse is chosen based on the maximum expected current and the circuit's requirements.

A failed diode can either open or short, affecting the circuit operation.
