If the amp meter is in series ahead of the first parallel branch of lamps the meter will read an increase in current.
If one lamp in a parallel circuit burns out, the other lamps are unaffected because current still flows through them. Total current in the system is reduced by the loss of the burned out lamp, which will raise voltage ever so slightly. That will have the effect of brightening the other lamps, but that effect is inconsequential unless there is significant impedance in the source or in the path to the lamps.
Incorrect answerThen only one of the lights go out.Correct answerActually ALL the lamps will go out if a short circuit occurs across any branch of a parallel circuit because, if the wiring has been done correctly, a circuit breaker will trip or a fuse will blow to cut off the supply of current to all the lights.The loss of a single lamp indicates a break, not a short circuit.
It is a series circuit, where all the lamps (for instance) is on the same wire. If one lamp fails, the rest lamps will also go out.
Nothing will happen to the possible output power of the power source i.e it will not increase. Each power source has its maximum possible output power. Adding more lamps in parallel will result in a drop in the circuit's total resistance which causes the total current drawn by the lamps to increase. Your wires might be burnt as a result so be careful.
When the lamps are in a loop, one after the other: we call this a series circuit.
In a series circuit, the current is the same throughout all components. Therefore, both ammeter 1 and ammeter 2 will read the same current, as they are measuring the same flow of electrons in the circuit. The readings on both ammeters will be equal, so neither will have a bigger reading. The voltage drop across the lamps may differ, but that does not affect the ammeter readings.
The lamps will get dimmer. In a parallel circuit, voltage is constant. Whereas, in a series circuit, amps are constant.

2 amperes in a parallel circuit. I = W/V. It is true provided that 12v are delivered to the lamps in parallel circuit. In a series circuit, the voltage is divided among the lamps so that the total current is probably 2 amperes for all lamps.
No. Plugs, lamps and 220 V a.c. items are in parallel with the breakers.CorrectionAll loads are in parallel with the supply voltage, but in series with the circuit breakers or fuses.
The first lamp will go out. ANSWER: any lamps in series the first or the last if unscrewed will cause all lamps to extinguish no matter whether the source potential is in series or parallel
If lamp C burns out in a circuit where lamps A and B are connected in series with lamp C, then both lamps A and B will also go out. This is because the circuit is incomplete when lamp C fails, preventing current from flowing through lamps A and B. In a parallel circuit, however, if lamp C burns out, lamps A and B would remain lit as they have alternative paths for current. The specific behavior depends on how the lamps are connected in the circuit.
If one lamp in a parallel circuit burns out, the other lamps are unaffected because current still flows through them. Total current in the system is reduced by the loss of the burned out lamp, which will raise voltage ever so slightly. That will have the effect of brightening the other lamps, but that effect is inconsequential unless there is significant impedance in the source or in the path to the lamps.
If the fuse of lamp S went out, the lamps that remain lit would depend on how the circuit is configured. In a series circuit, all lamps would go out since the circuit is broken. In a parallel circuit, only the lamp connected to the same fuse as lamp S would go out, while the other lamps connected to different fuses would remain lit.
