Accidents with explosives are far from unknown and the unaware, untrained and uncaring are most often the ones involved in causing the incident. The point of contact between the rod and the metal surfaces gets heated to the melting point, fusing a part of the rod and both surfaces into a single piece. Do be careful, the squib is the explosive device which inflates the airbag, as with all explosive devices the only way to be adequately safe when they are initiated is to be far enough away from them. The power supply for an arc welder can supply very high currents that flow through the welding rod and the metal pieces being welded.
If a charged, high-voltage capacitor is short circuited by a thin wire, the resulting huge current and power dissipation will cause the wire to actually explode.Īrc welding is a common example of the practical application of the heating due to a short circuit. Short circuits can produce very high temperatures due to the high power dissipation in the circuit. If it is a battery that is shorted, the battery will be discharged very quickly and will heat up due to the high current flow. a control circuit which causes the main switch to close when the control circuit detects a collision.

If a fuse is in the supply circuit, it will do its job and blow out, opening the circuit and stopping the current flow.Ī short circuit may be in a direct- or alternating-current (DC or AC) circuit. This results in excessive current flow in the power source through the 'short,' and may even cause the power source to be destroyed.
Answer A short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit.
