When a positive voltage is applied to anode of the diode from the circuit, more holes are able to be transferred to the depleted region, and this causes the diode to become conductive, allowing current to flow through the circuit.

When the plastic is cool, the carbon grains are all in contact with each other, forming a conductive path through the device.

When the gate is more positive, it attracts electrons, inducing an n-type conductive channel in the substrate below the oxide, which allows electrons to flow between the n-doped terminals ; the switch is on.

When a radio antenna is mounted above a conductive surface such as the earth, the radio waves directed down toward the surface reflect off it.

When both A and B are high, both transistors are conductive, creating an even lower resistance path to ground.

When is inside a conductive medium such as a thick slab made of copper or aluminum, it more readily reacts to the emf sent to it by.

When molten, the flux becomes conductive, and provides a current path between the electrode and the work.

When installed between wall studs, even perfect wall insulation only eliminates conduction through the insulation but leaves unaffected the conductive heat loss through such materials as glass windows and studs.

When a virtual ground, such as a finger, is placed over one of the intersections between the conductive layer some of the electrical field is shunted to this ground point, resulting in a change in the apparent capacitance at that location.

When the radio signal from a " dot " or " dash " came, the coherer would become conductive.

When the potential gradient ( electric field ) is large enough at a point in the fluid, the fluid at that point ionizes and it becomes conductive.

When the air near the point becomes conductive, it has the effect of increasing the apparent size of the conductor.

When the key is pushed down, the conductive material on its underside touches the pair of fork-shaped traces below, bridging the gap between them and closing the circuit.

When the key is pushed, the conductive underside makes contact with the traces on the bottom layer, and bridges the gap between them, thus completing the circuit.

When a conductive loop experiences a changing magnetic field, from Lenz's law and Faraday's law, the changing magnetic field generates an Electromotive Force ( EMF ) around the circuit.

When a sufficiently high voltage is applied across the amorphous silicon it is turned into a polycrystalline silicon-metal alloy with a low resistance, which is conductive.

When there is a potential difference between the rolled metal layer and the transparent conductive layer, the electric field formed between the two electrodes causes the rolled micro-blinds to stretch out and thus block light.

When a Weber test is carried out, sound localizes to the ear affected by the conductive loss.

When an electrically conductive pot is brought close to the cooking surface, the magnetic field induces an electrical current, called an " eddy current ", in the pot.

When an electrically conductive fluid flows through the tube, in the presence of a significant perpendicular magnetic field, a charge is induced in the field, which can be drawn off as electrical power by placing the electrodes on the sides at 90 degree angles to the magnetic field.

When a conductive projectile is placed between the rails, the circuit is completed and a magnetic field is created down the rails up to the point of the projectile.

When fencing with electric equipment, a manchette, or sabre cuff, is used in conjunction with the lamé and electrically conductive mask to ensure that the entire target area forms a single circuit.

When this electric field strength exceeds what is known as the corona discharge inception voltage ( CIV ) gradient, it ionizes the air about the tip, and a small faint purple jet of plasma can be seen in the dark on the conductive tip.

When a small volume of electrically conductive liquid is exposed to an electric field, the shape of liquid starts to deform from the shape caused by surface tension alone.

When a projectile is thrown by hand, the speed of the projectile is determined by the kinetic energy imparted by the thrower's muscles performing work.

When the bomb reached the design height for this stage ( reportedly 2, 000 meters ) the membrane closed a circuit, activating the circuit between the radar altimeters and the projectile gun.

When the projectile leaves the barrel, this spin lends gyroscopic stability to the projectile and prevents tumbling, in the same way that a properly thrown American football or rugby ball behaves.

When emplaced, the howitzer's high volume of fire compensates in large measure for the lower explosive weight of the projectile compared to the Army's 155mm and 8-inch howitzers.

When a hollow-point hunting bullet strikes a soft target, the pressure created in the pit forces the material ( usually lead ) around the inside edge to expand outwards, increasing the axial diameter of the projectile as it passes through.

When the projectile is swaged into the rifling, it takes on a mirror image of the rifling, as the lands push into the projectile in a process called engraving.

When used in the anti-tank role, a projectile that uses a shaped charge warhead is known by the acronym HEAT ( high explosive anti-tank ).

When fired, however, instead of all the propellant blast following the projectile out the barrel, a large portion is allowed to escape to the rear, gaining a rearward directed momentum which is nearly equal to the forward momentum of the projectile.

When the projectile nears this point the electromagnet is switched off and the next electromagnet can be switched on, progressively accelerating the projectile down successive stages.

When the flux in the projectile lies in the linear portion of its material's B ( H ) curve, the force applied to the core is proportional to the square of coil current ( I )— the field ( H ) is linearly dependent on I, B is linearly dependent on H and force is linearly dependent on the product BI.

When wielded, it can shoot energy blasts from the hand or sword, fire projectile darts, and extrude whip-like grapples to attack or to climb.

When it reaches the base of the tube it hits a firing pin, which detonates the propellant and fires the projectile.

When the round is fired, the projectile is pushed off the spigot, but before the plug clears the spigot it is caught by a constriction at the base of the tube.

When fired the reaction gases ( with a momentum equal to the projectile ) expelled out of the back of the weapon compensate the force exerted on the projectile.

When a gun is fired, it initiates a spherical shock wave but the projectile also generates a conical wave.

When in flight, the main forces acting on the projectile are gravity, drag and if present wind.

When the projectile is fired, the sabot blocks the gas, and carries the projectile down the barrel.
