Resistor limits current, higher resistor lower current for the
same amount of voltage...
V=IR, that is if there is only real power...
Voltage is electric potential energy per unit charge...
Resistor limits the current so it affect the current... if will
only not affect the current if theres a open circuit at the
resistor... of cause if it is an open circuit then the resistance
of that path can said to be infinity thus no current will flow
through it... example : during parallel circuit, more current flow
through the smallest resistance and less current flow through the
largest resistance...
