missing some basic theory

Hi New Dude,
Neither voltage nor current goes in circles in a parallel circuit.
In your schematic, both resistors have the same voltage. The current in each one is determined by Ohm's Law (I= E/R). Their resistance in parallel Rp is also determined by Ohm's Law when you add their current into It (Rp= E/It).

If both paralleled resistors have the same value, their parallel resistance is half of one of them.
3 equal resistors in parallel = 1/3 of one of them.
4 equal resistors in parallel = 1/4 of one of them.
etc.

Just remember that resistors in parallel increases the current because thier value is approaching a short circuit that causes a very high current. ;D

i know when you put resistors in parrallel they lower in value, but is it because of voltage or current, (or is it both) going in circles, could use some help.

Here is a nice tutorial on series and parallel resistors that is not related to food:

Hope it helps.

Hi,
Here i would like to put in some apt analogy than Food.
Electrons take lesser time to travel throgh lesser resistances like we do in lesser conjusted roads.
So more current flows through lesser resistances as current is rate of flow of electrons.
If we connect two resistors in parallel would be similar as 2 parallel conjusted roads and the total no of electrons flowing through will be sum of electrons flowing through both the resistors.
hence effective current increases for the same P.D
since R=V/I
the resistance decreases
