This means that the electric potential at the stream flowing into the resistance power is less than the potential at the point where it flows out of a resistor because electrical resistance has occurred in this resistance.
This means that the voltage at the point where the stream flows into the resistor is less than the voltage at the point of discharge resistors. Due to electrical resistance occurs in this resistor.
Means that the electric potential at the point of current flows through the resistor is less than a voltage at the point that flows out of the resistors. Due to the electrical resistance occurs in the resistor.
