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 you use a non-dimmable Compact Fluorescent Lamp (CFL) in a circuit controlled by a dimmer switch no damage will be done but the CFL will stay bright when the dimmer is turned down whilst any other normal incandescent lamps wired into the same circuit will go dim in the normal way.Dimmable Compact Fluorescent Lamps are now available, for example in the Megaman range of CFLs. For more information see the Related Link shown below.Incandescent dimming uses any incandescent lamps and an incandescent dimmer.To dim fluorescent lamps usually requires use of fluorescent dimmers AND fluorescent dimmable ballasts. If these two components do not match, dimming will not work.The fluorescent lamps themselves are the same whether you put them in a standard (nondimming) ballast or a dimmable ballast.If your dimmers are not dimming the CFLs they are either not fluorescent dimmers or, more likely, your ballast in the light fixture is not a dimmable ballast.
The letters "NC" on an electrical switch stand for "Normally Closed." This means that in the default position, the circuit is closed and allows electricity to flow. When the switch is activated, the circuit opens and interrupts the flow of electricity.
All Circuit Breakers have a current rating and a FAULT current rating. The current rating refers to the current at which the circuit breaker is designed to 'break' the circuit and this is generally shown in Amperes (A). FAULT current rating is generally alot higher rating and is therefor shown in kilo Amperes (kA). This kA rating refers to the amount of current which a circuit breaker is designed to handle under fault conditions and can still maintain operation and 'break' contact. Most household circuit breakers are around 7.5 kA, so any fault over 7,500 Amperes could potentially damage the circuit breaker contacts to the point which it can not open the circuit. Larger fault ratings are found in larger applications such as MCC's on plants, minesites or power stations.
Each appliance has its own amperage. This can be shown by looking at the label of each appliance. A circuit is protected by a breaker which has a trip limit. By continually adding more amperage from different appliances, the circuit becomes overloaded. When the circuits limit is reached because of the additive effect of more appliances to the circuit the breaker will trip. This disconnects the appliance loads from the distribution panel supply and prevents over loading of the conductors of that circuit. Without removing some of the load amperage, the breaker will keep tripping when reset.
Option 1: Use a circuit breaker. The breaker is essentially a switch that will turn off the electricity in the event of a current overload fault occurring somewhere either in appliances connected to the circuit or to the circuit's own wiring. Option 2: Use a fuse. Will turn off the electricity in the event of a current overload. One downside is that fuses destroy themselves in order to cut-off the power, so you have to replace them. Another downside is that some of the simpler types of fuse are not as fast-acting as a circuit breaker so they can allow more damage to occur before they shut off the supply of current.In reality, unlike a circuit breaker, a fuse is not really an "overload protection device" but a "device for opening a circuit which has a higher current subjected to it than it was designed to carry", such as a short circuit condition.For example certain types of electric motor need to draw a high start-up current so a circuit feeding such a motor must be fused at up to 250% of the motor's rated running current or Full Load Amperage (FLA). So a motor could be in an overload state up to 200% over its FLA and still not blow the fuse.

In the circuit shown, there are potentially three different currents.

A closed circuit is a kind of electric circuit in which the path that the electrons follow forms a complete circuit.
There is no circuit shown in your question. It is not possible for us to see your homework paper and answer this question.
No because a circuit without power applied can only be shown to be a short circuit after the power is applied between the 'right' two points.
You may well need to replace the small bulbs/lamps behind the dash.

if the value of the reactive component was increased, how would it change the waveforms?

Lamps will only operate at their rated power when subjected to their rated voltage -which is why you will see both figures shown on the glass envelope (e.g. 60 W / 230 V or 60 W / 120 V, etc.). If you connect lamps in parallel, because each branch is subject to the same voltage (i.e. the supply voltage), each lamp has the same voltage applied and will operate at its rated power. If you connect lamps in series, the supply voltage will distribute itself as a series of voltage drops where the sum of the voltage drops will equal the supply voltage. So none of the lamps is subject to its rated voltage, so none will operate at its rated power -i.e. they will be dim!
