No. You can have multiple devices on a series circuit. How about a low voltage Christmas tree light set. There you may have 15 or 20 lamps in series.
series circuit
It is called a series circuit.
All of the light bulbs in the series circuit would go out.
It is a series electrical circuit.
parallel
A series circuit is one in which the current must pass through all the electrical devices in the circuit in turn. A parallel circuit is one in which the current passes through each electrical device on the circuit following separate, independent path from all other devices on the circuit, one for each electrical device.
series circuit
The most common of all circuits used in industry and around the home is the parallel circuit. In industry all MCC controls are in parallel with the supply distribution and around the home all lighting circuits are in parallel with the supply distribution panel.

to assemble a circuit you just need to connect one end of a wire to the battery and the other to the light bulb ( could be another electrical device) now take an other wire and connect on end of it to the other side of the battery and the other to the other side of the light bulb( or an other electrical device. if your circuit is including a switch this is how you do it: ( you will need three wires for this circuit if you have one electrical device) connect one end of the wire to the battery and the other to the switch.Grab another wire and attach one end of it on the other side of the switch and the other to the electrical device (light bulb). Grab another wire and attach one end of it to the other side of battery and the other to the other side of your electrical device. And there you have it how to assemble a circuit
Parallel circuits are used when there are many electronics on the same circuit, such as Christmas lights, for example. If they were on a series circuit, if one bulb went out all of them would go out. In your home, parallel circuits allow you to turn any electrical device on or off, independently of the others.
By definition, more than one. If a circuit has just one path, it is a series circuit, not parallel.
The terminology down stream refers to an electrical circuit and where devices are connected into the circuit. In reference to the breaker that feeds the circuit everything is down stream from it. If a GFCI receptacle is added into the circuit as the first device, the GFCI can be wired to allow all of the regular receptacles to be protected down stream from that GFCI. Every device added to the circuit will be down stream from the one that is ahead of it. The only device that will not have something down stream from it will be the last device in the circuit.
