A shunt resistor, which has been connected in parallel across the filament before it burnt out, will then short out to bypass the burnt filament and allow the rest of the string to light. If too many lights burn out however, a shunt will also burn out, requiring the use of a multimeter to find the point of failure.

(Equivalent to IEC 60750 Edition 1.0, 1983.) IEC 113 (Superseded by IEC 750, i.e. IEC 60750.) IEC 750-1983 (AS 3702 is equivalent, but provides extra information.)
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
A voltage-regulator tube (VR tube) is an electronic component used as a shunt regulator to hold a voltage constant at a predetermined level. Physically, these devices resemble vacuum tubes, but there are two main differences: Their glass envelopes are filled with a gas mixture, and
The first rubber-insulated cables for US building wiring were introduced in 1922 with US patent 1458803, Burley, Harry & Rooney, Henry, "Insulated electric wire", issued 1923-06-12, assigned to Boston Insulated Wire and Cable . These were two or more solid copper electrical wires with rubber insulation, plus woven cotton cloth over each ...
In fact, the power loss due to heating in the transistor is the current multiplied by the voltage difference between input and output voltage. The same function can often be performed much more efficiently by a switched-mode power supply , but a linear regulator may be preferred for light loads or where the desired output voltage approaches the ...
Shunt resistor. The common and simple approach to current sensing is the use of a shunt resistor. That the voltage drop across the shunt is proportional to its current flow, i.e. ohm's law, makes the low resistance current shunt a very popular choice for current measurement system with its low cost and high reliability.
Some common DC power connectors. A DC connector (or DC plug, for one common type) is an electrical connector that supplies direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent ...
