Answer:
Resistors are connected to a power source, of any kind, they will inhibit the flow of electricity. How much they do that is given by Ohms’s Law.
A switch on the other hand, only has two conditions, either Open Circuit or Closed Circuit. There is no in-between as there are with semiconductors, and resistors.

- The device that allows a circuit to be opened is a switch. The one and only way for a network to work for it to be closed. Such continuity is broken by a switch.
- A resistance allows electrical current flows through, but it slows things down in some way.
- In a closed-loop, it narrows each electrons' route, lowering the overall current.
- In a closed network, a switch provides an open circuit, while a resistor minimizes the current.
