Comparing parallel voltages with the water analogy do u think the two loads separating from the main pipe will experience the same push on them...
if the water flow in the main pipe is now doubled then how does the generator double the water flow without increasing the push..
(how can the voltage source supply double the the current without increasing the voltage ?? since naturally more push by the generator only will give rise to more current flow through the pipe
Two resistors in parallel have same voltage across them whether they have same resistance or not. This can be understood using water analogy as follows:
Consider a pipe with dimensions: length(l), cross-sectional area(area seen when we cut the pipe perpendicular to direction of water flow, just to remind;-)) as A. Now if we pass some amount of water from 1 end, it would require some time to come out from other end. Now, if we increase the length of the pipe to 2l, then for same amount of water we wold require double time. Similarly if A becomes 2A time required is half since more area available for the water to flow. This characteristic is termed as RESISTANCE. Replacing amount of water by amount of(or precisely, no. of) electrons, we get current. Now, we can imagine that double time is required for same no. of electrons if area is halved or length doubled. This same statement can also be stated as half no. of electrons are obtained in a given fixed amount of time if area halved or length doubled.
Now, consider 2 pipes with same dimensions connected in parallel to each other. Now, if we pass some amount of water from their top end(considering your diag.) we get same amount of water in same time i.e. equal current flow from both pipes. Now, if left pipe's length is doubled, then for a given amount of water, left one requires double time than right pipe or if we observe both pipes for same time, half amount of water flows through left pipe than that in right pipe. So, half current in left pipe than that in right one. However the voltage across both remains same.
Now to your question, if the resistances or the voltage source are not changed, current will not change. For current to change, pipe dimensions or generator's potential, either of two must be changed otherwise, amount of water flowing through any part will not change. Now, having supply with more current capacity does not cause more current to flow since the source having more capacity does not implies it would always cause that much current to flow. This is similar to having bigger water tank at same potential or height (i.e. more capacity), but passes same amount of water in same amount of time due to same pipes connected to it.
Hope this essay clears your mind. Feel free if any more such doubts are there. Making them clear in the initial stage is better than getting frustrated again & again in future.
