this is maybe one basic question, i drew 2 connections of capacitors, the left : connected in series. the right : connected in parallel ??

yes you are right, as the current splitted at the nodes will be constant through the 2 capacitors and the wire that doesn't carry capacitor is shortedaxmls said:The left is in series, but the right is not in parallel. They are also in series (but they are short-circuited).
Two elements in parallel have the same starting node and the same ending node, and have the same voltage across them.
so is this a connection in parallel ?axmls said:The left is in series, but the right is not in parallel. They are also in series (but they are short-circuited).

yes but i mean in this position they are in parallel also, because there are people that link parallel/series to exact position which is not totally right, the main thing that components having same current passed in them are series and others are parallel regardless of exact positionrumborak said:If you move the left capacitor along the wire to the top, if becomes obvious.
No, it's not "not totally right" it is totally wrong. You can always redraw circuits to look weirdmohamed el teir said:yes but i mean in this position they are in parallel also, because there are people that link parallel/series to exact position which is not totally right
Exactly., the main thing that components having same current passed in them are series and others are parallel regardless of exact position

mohamed el teir said:does that mean that it is not right to decide for any connection having no battery if it is in series or parallel ?
what about a component having a high voltage (like a charged capacitor) connected with components of lower voltage and without voltage source in a circuit of one loop, won't this highest voltage component act like a voltage source, leading to a current passing in the circuit (decreasing the voltage of the highest voltage component and increasing the voltage of others) till the sum of voltages of the other components becomes equal to the voltage of highest voltage component, i mean the other components are like to be connected in series with each other and in parallel (if we talk about them as a one unit) with the highest voltage component, and if the circuit from the start was of 2 components they will be like to be connected in parallel (one's voltage is decreasing and other is increasing till they become equal)Drakkith said:It means that without a voltage or current source (or at least without knowing how the source will connect to the circuit) you cannot determine whether the two components are in parallel or series.
why kirchhoff, we're just talking about one loop, and it is logical any way that current will pass till the circuit become equipotentialrumborak said:Mohamed, I think at this point you have arrived at a complexity of your circuit that you really need to familiarize yourself with circuit analysis (e.g. Kirchhoff rules etc.). Any textbook about the subject will do.

is this right or what
mohamed el teir said:i will try to correct it and make it more clear :
1st case : consider a component with voltage V1 and other component with voltage V2 where V1 > V2. if they are connected in a circuit of one loop only and without voltage source : there will be current I due to the potential difference in the circuit, V1 will decrease and V2 will increase till : V1 = V2.
2nd case : consider a component with voltage Vmax and other n components with voltages V1, V2, V3, ... Vn respectively where Vmax > V1, Vmax > V2, ... Vmax > Vn. if they are connected in a circuit of one loop only and without voltage source : there will be current I due to the potential difference in the circuit where I is constant through the n components, Vmax will decrease and V1, V2, ... Vn will increase till : Vmax = V1 = V2 ... = Vn.
how true is this ?
mohamed el teir said:@Drakkith
I will modify case 2 and tell me how true it is :
consider a capacitor C with voltage V and charged to Q, and other n capacitors C1, C2, C3, ..., Cn which are uncharged and so have voltages = 0. if they are connected to each other in one closed loop only and without voltage source : there will be current I due to the potential difference in the circuit where I is constant through the n capacitors (and so q lost by C will be constant through the n capacitors, so that each capacitor from : C1, C2, ..., Cn will be charged to q). V will decrease and voltages of n capacitors will increase till : V = V1 + V2+ ... + Vn, more precisely : (Q-q)/C = q/C1 + q/C2 + ... + q/Cn
In a parallel connection, the components are connected side by side, allowing the flow of current to divide and flow through each component separately. In a series connection, the components are connected end to end, with the current flowing through each component in order.
A series connection is better for increasing the overall resistance because the total resistance is the sum of the individual resistances. In a parallel connection, the total resistance is less than the smallest individual resistance.
In a parallel connection, the voltage across each component remains the same, while in a series connection, the total voltage is divided among the components. This means that in a series connection, the voltage across each component is less than the total voltage.
Yes, you can mix components in a combination of parallel and series connections. This is known as a complex circuit and is commonly used in electronic devices to achieve desired results.
A parallel connection is generally considered safer because if one component fails, the others will still function. In a series connection, if one component fails, the entire circuit will fail. However, proper safety precautions should be taken in all types of connections to prevent accidents.
