In a simple parallel circuit, a single charge will pass through one resistor or the other, not both. Therefore the voltage must all be used in the resistor it passes through, which is why both resistors receive the same voltage drop.
Because the wires connecting the ends have very low resistance and thus zero current difference. The same voltage across two resistances results in different current flow in them.
Components in parallel always have the same voltage across them because they are connected to the same points.
Assuming steady state DC, voltage can only exist across a resistance. Well, or a capacitor. But since we're talking about wires and resistors, if R is zero, IR will also be zero. And the imaginary wire connecting the two resistors(talking schematic here and not the real world) has no resistance, and therefore no voltage drop across it.
In parallel circuit having no neutral in between 2 resistance.So voltage is same
But series circuit having neutral (e.g) + - + - the center having (- +) in the e.g act as neutral 0 V so series circuit shares the voltage
That is what in parallel means, ie two paths between the same two voltages.
Because voltage source applies to both resistors at the same joints, But the current will be different if both resistors value are not the same.
