How do you connect series circuits?
The two ways to connect components in a circuit are in series and in parallel. In a series connection, components are connected end to end, so that current flows first through one, then through the other. In the series connection, the current goes through one lamp and then the other.
How is the brightness in the 2 circuits related to charge flow or current?
Brightness gets dimmer since less current or charge passing through each bulb AND smaller voltage drop across each bulb (the voltage gain at the battery is now distributed among 3 bulbs as opposed to just one). Circuit B would have only 1A of current.
How do combination circuits work?
A combination circuit is one that has a “combination” of series and parallel paths for the electricity to flow. Its properties are a combination of the two. In this example, the parallel section of the circuit is like a sub-circuit and actually is part of an over-all series circuit.
What happen if you add another bulb to both of your circuits Why?
When you plug in that second bulb, both will get equally dim, because you have added more resistance to your circuit, which decreases the flow of current. Adding another light bulb in series decreases the current because our battery now has more work to do! You just add all of the different resistance values together.
How is Circuit 2 connected to circuit 1?
Since the load for Circuit 2 doesn’t have a matching neutral, it’s connected to Circuit 1’s neutral line. And before you ask, Circuit 1 and 2 are not MWBC circuits. Each one can be turned on/off independently.
How does mutual inductance in a circuit work?
The amount of mutual inductance that links one coil to another depends very much on the relative positioning of the two coils.
Where can you find two circuits sharing a neutral?
A multi-wire branch circuit (two hots from different phases sharing 1 neutral) is often found in the kitchen where it powers one receptacle which has the jumper connecting the upper and lower outets removed. The result is that you get two 15amps circuits at one receptacle.
Can a circuit be turned on and off at the same time?
That way both circuits will always be turned on/off at the same time. That is precisely a Multi-Wire Branch Circuit (or MWBC). Those are defined as exactly what you drew: 2 hots that share a neutral up to a point.
