How is it possible that in scenario 1 resistor
R1 converts 5V of energy to heat and in scenario 2 the same resistor
R1 converts 2.5V of energy to heat?
R1 in both scenarios are exacly the same, I don't seem to grasp what happens on the physical level to the electrons how they "know" when to dump all their energy at once in resistor
R1 in scenario 1 or to divide the energy they have proportionally over the resistors
R2 in scenario 2.
I have read an explenation here, but it's still not clear. How is it possible that the voltage is different at point
A going through the same amount of resistance? I would expect a linear relation between voltage and resistance.
Could someone explain what physically happens that causes this?
Is my understanding right? According to here
The resistance drops liniar along the path.
In scenario 1 at the start of
R1 the resistance the current encounters is 100\$\Omega\$ and at the end of
R1 it encounters 0\$\Omega\$.
In scenario 2 at the start of
R1 the resistance the current encounters is 200\$\Omega\$ and at the end of
R1 it encounters 100\$\Omega\$.
If this is true, why does point
A in scenario 2 have more volt left if it has encountered a higher resistance of 200\$\Omega\$ at the beginning opposed to scenario 1 where it encountered 100\$\Omega\$ at the beginning?
