Do you wire 12 volt down lights in series or parallel?
Parallel.
What is the smallest size wire that can be installed in a parallel permitted by the nec?
1/0 wire
How do you connect a 3 wire fixture to a 2 wire fixture that are connected to the same switch what do you connect the red wire to?
A three wire fixture most likely is one that has two separate loads within it. An example is a ceiling fan with a light fixture. If the three wire is used to separately switch the two loads you have to make a decision as to which load you want to work with the two wire fixture. Once that decision has been made connect the two wire fixture in parallel with the your selected load on the three wire fixture. On these types of installations the three wire fixture is usually controlled by two separate switches in a two gang box. The red and black wires of the three wire terminates on the bottom of either switch. The white wire is connected to the incoming neutral. The top of the switches are paralleled together with the "hot" feeder from the distribution source.
What is the minimum wire size for desk lamp cords?
Most lamp wire is parallel #16 conductors.
What does a Three wire installation provides a power source for?
It could be a number of things in electrical terminology. Three phase. Single phase three wire. Three wire stop start control. Three wire speed control.
If one of the three lamps blows out when connected in parallel what happens to the current in the other two?
Nothing
If one of three lamps blows out when connected in parallel what happens to the current in the other two?
If three lamps are connected in parallel and one blows out, the current in the other two does not change. This assumes that the net change in total current does not cause the power source to change voltage.
In which case will there be more current in each of three lamps- if they are connected to the same battery in series or in parallel?
more current will be in case of parallel because in series combination resistence is greater with respect to parallel combination
As you add more lamps to a parallel circuit what will the ammeter reading do?
If the amp meter is in series ahead of the first parallel branch of lamps the meter will read an increase in current.
How could you determine whether a string of lights is in series or parallel BEFORE you purchase?
if the lamps are standard edison or medium they may be parallel lamps smaller than your finger are series
What happens to the power output of each lamp if more lamps are connected in parallel?
The lamps will get dimmer. In a parallel circuit, voltage is constant. Whereas, in a series circuit, amps are constant.
Why do you connect electrical lamps in series?
If you are referring to house wiring, then you don't normally connect lamps in series with each other; they are normally connected in parallel with each other. When lamps are connected in parallel, each lamp is subjected to the same voltage; providing this is the rated voltage of each lamp, them each will operate at their rated power.If you did connect lamps in parallel, the you would find that the lamps with the higher power ratings will be dimmer than the lamps with the lower power ratings -which is not what you might expect!
How do you calculate the current flow through a parallel circuit with three lamps each of 48 ohms?
To calculate the current in the parallel circuit we need the concept of ohms law, V=IR we know the resistance, R=48 ohms voltage will be constant as 220-230 volts so, I= V/R = 230/48 = 4.791 A Add currents of three lamps, ie., I = 14.375
Are the lamps in buildings connected in parallel or series?
No. They are connected in parallel with each other.
If both series and parallel circuits have 1 cell and 3 lamps, which type of circuit would be brighter?
Parallel circuit.
If a 12 volt parallel circuit has 3 lamps what is the current?
See discuss.
Do you wire 12 volt down lights in series or parallel?
Parallel.
