    It's like a roadblock. Some of the electron's kinetic energy is transferred to the resistor atom's thermal energy. The resistor heats up, the electrons have less energy coming out the other side. This is why it's called a voltage drop, you lose potential energy.

    Resistor is a device used in electrical circuits.
