How does a shunt resistor work
One example is in miniature Christmas lights which are wired in series. When the filament burns out in one of the incandescent light bulbs, the full line voltage appears across the burnt out bulb. 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 po… WebA shunt resistor is used in an electrical circuit to protect against overvoltage. It is used in a current measuring device. It is used to bypass defective devices. (When a number of components are connected in series, one component is failed to operate, it will break the entire circuit. What causes shunt resistance?
