Series circuit

A series circuit is a connection configuration in which the terminals of the devices (generators, resistors, capacitors, inductors, switches, among others) are connected successively, that is, the output terminal of one device is connected to the input terminal of the next device.

Following a simile hydraulic, two water tanks will be connected in series if the output of the first is connected to the input of the second. An electric battery is usually made up of several electric batteries connected in series, in order to achieve the voltage that is required.

Depending on the devices connected in series, the total or equivalent value is obtained with the following equations:

• For generators (piles)

VT=V1+V2+...+Vn{displaystyle {V_{T}}={V_{1}} +{V_{2}} +...+{V_{n}}{,}

IT=I1=I2=...=In{displaystyle {I_{T}}={I_{1}}={I_{2}}=

• For resistances

RT=R1+R2+...+Rn{displaystyle {R_{T}}={R_{1}} +{R_{2}} +...+{R_{n}}{,}

• For capacitors

1CT=1C1+1C2+...+1Cn{displaystyle {1 over C_{T}}={1 over C_{1}}}}+{1 over C_{2}}+...+{1 over C_{n}}},}

• For switches

Interruptor A	Interruptor B	Interruptor C	Departure
Open	Open	Open	Open
Open	Open	Closed	Open
Open	Closed	Open	Open
Open	Closed	Closed	Open
Closed	Open	Open	Open
Closed	Open	Closed	Open
Closed	Closed	Open	Open
Closed	Closed	Closed	Closed

Another possible configuration, for the arrangement of electrical components, is the parallel circuit. In which, the equivalent values are calculated inversely to the series circuit.

It is important to know that to add the magnitudes, only in alternating current, it must be done in factorial (vectorial) form, to be added in a modular way, each branch must have a maximum of one element.
