Parallel circuit
elelctric current
An electric current involves the flow of electrically charged particles - usually electrons, but it may also be other particles, with a positive or negative charge. Now, to say that an electric current "is" a flow of charged particles is an oversimplification - the situation is a bit more complicated.
Heat is caused by resistance against electricity, or flow of current which is part of electricity. Electricity was made by physical power converted into electricity. The heat is caused by resisting the flow of electrical current.
it just does The thicker the wire the more space there will be for electrical current to flow. What this means is that the electrons have a lesser chance of hitting the atoms and causing resistance.
Parallel circuit
The current branches, so that part will go through one branch of the parallel circuit, and part through the other branch. (It is also possible to have more than 2 branches.) Then it joins again.
A Counter-current flow has more advantages as comapared to a co-current flow.
Counter-current flow is more efficient then parallel flow. Shahzad, MUET Chemical Engineer
In any parallel connection The original current gets divided into the parallel branches, however the division is solely based upon the resistances of the parallel paths. Current always tries to flow through the branch having the least resistance. Thus More current will flow in the branch having less resistance and vice-versa. The currents flowing in the parallel branches can be found out by using the current divider rule. Suppose if R1 & R2 are two branches of a parallel connection & i1 & i2 is the current flowing through them respectively. Let 'I' be the original current then the current through R1 can be given as i1=R1/(R1+R2) * I similarly current through R2 can also be calculated.
Electric current is the rate of flow of electrons.AnswerA more accurate definition of electric current would be that it is a flow of electric charges. While current flow in a metallic conductor is, indeed, a flow of electrons, in other conductors -such as electrolytes- current flow may be a movement of ions. So, it would be more accurate to define current in terms of charge flow, rather than in terms of electron flow.
elelctric current
Electron flow, or just current. The more electrons flowing per second, the higher the current.
Answerits lightning, for a more simple answer......electric current flow is the movement of charges. Most often, however, we consider electric current flow to be moving electrons, or electron current flow.We most often use the term electric current flow to refer to the moving electrons, the flow of which is measured in amperes.Earlier scientists, before the discovery of electron, do believe that current flows right from positive terminal to the negative. This is known as conventional current flow.So electron flow is always opposite the direction of conventional current.
To be more accurate, current flow consists of electrons flowingfrom generator, through load and back to generator.

If it is spherical then where/how does the current flow?
