relation of series circuit to direct current?

Answer 1

direct current series circuit the voltage stays the same .... but in parallel the voltage divides depending on the resistance in each of the branches

Answer 2

openpsychy is correct...the current through resistors in a series is the same. Think of the wire as a rubber hose; think of the house connection to that hose and the nozzle of that hose each as a resistor. Now turn on the water at the house connection...what happens? Nothing. Why? Because you haven't opened the nozzle yet.

Now open the nozzle wide open...what happens? Plenty. Water spews forth out of that nozzle and wets your yard. But, because the house connection and nozzle are in series (one follows in line behind the other) the water at the connection is flowing just as fast and hard as the water at the nozzle.

The water has to be flowing at the same rate throughout the hose because, if it were otherwise, the water would accumulate and blow out the hose. That follows because somewhere along that hose the water behind would be flowing faster than the water in front. That clearly cannot be without damaging the hose. The water has to be flowing evenly throughout the hose. That water is the current in a DC series circuit.

Now start to close that nozzle a bit to diminish the flow of water. In electrical circuits, closing the nozzle a bit is like adding resistance to a variable resistor. So just like the flow of water lessens when closing the nozzle, the flow of electrical current slows when adding resistance in a series. And, once again, that flow rate has to be the same throughout the hose; the same thing for electrical current in a series circuit...it has to be the same throughout the wire.

Answer 3

Well the flaw in this question is that a series circuit doesn't care if current is direct or alternating.

In series circuit there is only 1 path for current so current is constant at all points of circuit and voltage varies according to resistance
In Parallel circuit there are multiple paths for current so the voltage is constant while current varies according to resistance

DC current is unidirectional and constant..AC current is in flux and bidirectional.

So you are asking apples vs oranges question

Answer 4

this is not really a question that I can answer. Can you be a bit more exact about what you want to know? The way you have it written I don't see how to answer it.

In a DC series circuit, the current flow is through the circuit, but that doesn't seem like much of a question.

Answer 5

Direct Current (DC) is opposite to Alternative Current (AC):

AC and DC has to do with the electric source (battery,generator,...).
If the electric source has invariable poles (such as a battery), the produced current is Direct Current. But if the electric source has variable poles (namely,that the + and - poles are changing constantly) (such as in a generator), the produced current is Alternative Current.
(see the differences between AC and DC here : http://www.pbs.org/wgbh/amex/edison/sfeature/acdc.html )


Series Circuit is opposite to Parallel Circuit:

Series or parallel circuit has to do with way you set up a circuit. It is said that two circuit elements are connected in parallel if the ends of one circuit element are connected directly (i.e. a conductor) to the corresponding ends of the other. However, when the circuit elements are connected end to end, it is said that they are connected in series. (Check this link out: http://en.wikipedia.org/wiki/Series_and_parallel_circuits)


Now, if you put a battery as the electric source in your circuit, whether your circuit is series or parallel, you will obtain "direct current" (because the battery produces direct current). Likewise, if you put a generator as the electric source in your circuit (we assume that it's possible!), wheter your circuit is series or parallel, the produced current is "alternative current" (because of the generator).

Answer 6

All the resistors are in series which means that the same current flows through all the resistance. Direct current comes from a battery.

Answer 7

As I remember, sequence circuits have one element after yet another, 3 resistors in a row. Parallel circuits have various circuits that are in "parallel" to a minimum of one yet another, allowing cutting-edge to run via each and all of the traces. AC is ability that flows lower back and forth, like what you plus into from the wall, and DC is one way cutting-edge, like a battery. whilst this does not answer the question precisely, i'm hoping it helps refresh your reminiscence. (BTW I quite have not theory approximately hassle-free circuitry in a pair years, so i'm hoping my explainations are comprehensible and applicable.)

Answer 8

Behaviour of series circuit is the same for DC or AC.

Answer 9

Suppose you have 3 resistances(R1,R2,R3) connected in series to a voltage source V.Let the current flowing thru the circcuit be i
then we have from kirchoff's laws
V=iR1+iR2+iR3=i(R1+R2+R3)
n a series circuit same current will flow thru all elements.
