Parallel curcuit 's current questionnaire?

Question

Why would the current in the wires closest to the source increases?

My guess: because the current are not splitted

Please give me your guidiance:)

Answer 1

Assuming that the wires closest to the source are either before or after the parallel branches in the circuit -- current would be max there because there is only one route for it.

Answer 2

Sir:

Current flows in wires because of a load that the wires are connected across and then plugged into a source.

If you only have one source and one load (Two Wires) a certain amount of current will flow based upon Ohm's Law ( Amps =
Volts / Ohms ).

When you connect a second load in parallel with the first
load, you lower the resistance of the total load upon the source,
so more current flows.....some into load # 1, some into load # 2.

Let's say the load, resistance # 1, was 4 Ohms.

If you connected a second load, resistance # 2, of 4 Ohms
in parallel with the first,

then the total resistance is now 2 Ohms (use resistance
formulas for parallel resistance to calculate this).

If the source voltage was 100 Volts, Using 4 Ohms as the
first load, the current would have been 100 / 4 = 25 Amps.

When you added another 4 Ohm load in parallel with the first,
your total load went down to 2 Ohms, and
100 / 2 = 50 Amps current flow.

As a result, you must keep current flows in mind for correct
sizing of wire conductors or overheating will result, and the
possibility of fires will increase dramatically.
