a bad connection
A circuit board error. Probably disconnected or obstructed.
parallel circuit
If the bulb's filament is broken, the whole circuit becomes open. If the bulb is in a series circuit or is the only bulb, the electricity would no longer flow. If the bulb is in a parallel circuit, along with other bulbs, then only the blown bulb would go out, and the other bulbs would still work.
There are only two things which cause fuses to "pop," or blow. 1. Electrical current flow [amps] in the circuit which exceed the amperage value of the fuse. This would be caused by a short circuit to ground, either inside the ecmb, or anywhere in the circuit wiring. 2. Very seldom, a fuse may be defective and simply fail "on its own."j3h.
Series connection has only one switch, what would happen if this kind of circuit were used in your home? All the appliances in the circuit would have to be turned on at the same time or none would work.Just think of your living room with all lights on, the radio playing and the television on - all at one time. If you turned off one of these, they would all go off.
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
A series/parallel circuit.
The parallel-tuned filter in antenna circuit rejects only the undesired frequencies.
The only way an Inverter could overload a circuit would be on the supply side. The fusing/protection for the inverter is incorrect.
A short circuit is a condition whereby a point or section of the circuit offer a short path for current to return to the power supply. It occurs when two or more points or sections of the circuit touches each others (but only and only if that results in drop in resistance to such an extent that it causes excessive current to flow through.
If you are saying that the secondary (output) winding on a transformer seems to be a short circuit, it is very likely to be low resistance and may only be a few ohms if you measure the resistance with an ohmeter. The only way it would actually be a short circuit is if something has been inserted which has shorted the wires or it has overheated and burnt through. In which case there should be an acrid smell. Or if you can see the wires you would see they were burnt. A short in the circuit it is powering could cause the transformer to overheat, burn out and short.
I you wired a light bulb in to the same circuit you have the possibility of over loading the circuit but other than that it would just be brighter.
