Short-circuit Operator
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an " open circuit", which is an infinite resistance between two nodes. Definition A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors. In circuit analysis, a ''short circuit'' is defined as a connection between two nodes that forces them to be at the same voltage. In an 'ideal' ...

Crossed Wires
In electronics, crosstalk is any phenomenon by which a signal transmitted on one Electronic circuit, circuit or Communication channel, channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive coupling, capacitive, inductive coupling, inductive, or conductive coupling from one circuit or channel to another. Crosstalk is a significant issue in structured cabling, audio electronics, integrated circuit design, wireless communication and other communications systems. Mechanisms Every electrical signal is associated with a varying field, whether electrical, magnetic or traveling. Where these fields overlap, they interfere with each other's signals. This electromagnetic interference creates crosstalk. For example, if two wires next to each other carry different signals, the currents in them will create magnetic fields that will induce a smaller signal in the neighboring wire.
