These slow down the flow of electrons (the current). Some of the electrons' energy are converted into heat or light. (Lessons 5.01-5.03) Question 1 options:

Conductors

Insulators

electric currents

Resistors

The unit that has been capable of the slow down the flow of current has been resistors. Thus, option D is correct.

In an electrical circuit, there has been the presence of wires that have been mediated the flow of current from one end to another. The flow of current has been the representation of the electrons transfer across the wire.

When there has been an interruption in the path of the electrons, there has been no continuous flow, and the energy has been converted to heat.

The conductors have been the object that has been capable of transmitting the continuous flow of current, The insulators have been the objects that have not been able to pass the electrons, and thereby are not allowing the current flow.

The electric current has been the flow of the electons itself. While resistors have been the unit that has been added to the system for the slowing down of electric current, and thereby the electron flow.

Thus, the unit that has been capable of the slow down the flow of current has been resistors. Thus, option D is correct.
