What is a parallel connection?
In electrical circuits series and parallel are two basic ways of wiring components. The naming comes after the method of attaching components, i.e. one after the other, or next to each other. As a demonstration, consider a very simple circuit consisting of two light bulbs and one 9V battery. If a wire joins the battery to one bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If, on the other hand, each bulb is wired separately to the battery it is wired in a parallel circuit.

Thanks for the feedback!
Parallel ports are generally used to connect printers.
A series connection will not work if one bulb fuses but in a parallel connection if one bulb fuses the rest will stay lit.
Twist the three pigtails together and solder them.
The voltmeter is connected in parallel.
Because it should not be connected in series
of course in parallel.... for the voltage har 2 b constant... and malfunctioning of one light will not affect other lights..... Answer Actually, in North America, i…t is common for street lights to be connected in series.
Ammeters must be connected in series with the load. When connecting in parallel the meter appears as a short. If you open the meter, there's usually an 850ma fuse, and/or a 2A… and 10A fuse that you can replace and fix the meter. Ohms, Volts, Inductance, Capacitance, Frequency, etc are all measured in Parallel, Only amps are measured in series. This is why there's always a separate "red" terminal for amps that you have to switch the lead to, so you know to connect it in series. If you're trying to measure the ampacity of something, E.G. "How many amps does this power supply put out? You'll need to rig up a load in series with the meter, large variable resistors which are carbon piles are commonly used to test the condition of automotive batteries and vehicle charging systems (alternators).
Paralleling generators The following is for three phase manual paralleling of two generators. Today's control systems will sense and do this operation automatically but the… general process is the same. There are a couple of factors that have to be met when paralleling generators. The process of paralleling generators is called synchronization. What this means is that both generators have to be in phase with each other and running at the same speed. The generator that is running is called the lead generator and the one that you are trying to parallel is called the lag generator. There are two types of instrumentation used in synchronising, one is a light bank and the other a bit more sophisticated is a synchroscope meter. The synchroscope indicates whether the lag generator is faster, slower or in phase with the bus. The lag generator is brought up to speed just under the RPM of the lead generator. The synchroscope will be revolving very slowly in a clockwise rotation at this point. When the hand on the synchroscope reaches the 11 o'clock position the switch is thrown to bring the generator on to the bus tying the two generators together.
1. bec the capacitor not allow the current to pass through it after it has charged & it charged in no time ex:(10^-4 second). 2. because it is necessary to avoid wrong polar…ity by shorting the terminals of the capacitor and tripping the fuse.

(1) To ensure that the voltage across each appliance is the same and equal to the supply voltage (otherwise none will operate at their rated power), and (2) to ensure that all… the other appliances continue to work should one appliance fail.
1.In series connection the total resistance is equal the total number of resistor that was connected in series 2.the current is constant in a series connection 3.in a se…ries connection total voltage is equal the number of of volt per cells
In series connection current will be same. in parrel connection voltage will be same and current wil be varying
if one bulb burn out the other do not goes out
In power distribution: Parallel transformers share load and so have a longer lifespanIf one fails and the other is capable of handling the entire load for a time, then the fa…iled one can be fixed without any outagesIf a network's load increases, then adding a parallel transformer increases the total deliverable power to meet this In AC/DC conversion (typically for HVDC): When a star-star transformer operates in parallel with a star-delta transformer, they "remove" a number of harmonic currents introduced by the switching devices, creating a cleaner waveform.
