Describe a system that would be dangerous if resistance were not a part of the circuit

A simple cord covered with rubber can be deadly. But a light bulb will surely produce no light if it is incandescent. 
Explanation:

A wire wrapped with rubber would be quite deadly. lightweight|a light-weight|a lightweight} bulb that was incandescent would in all probability not manufacture light in any respect.In fact, it are often quite dangerous to make (directly connecting the poles of a voltage supply at the side of one piece of wire). the rationale it's dangerous is as a result of the magnitude of electrical current could also be terribly giant in such a brief circuit, and also the unleash of energy terribly dramatic (usually within the variety ofheat). Usually, electrical circuits area unit created in such the simplest way on build sensible use of that discharged energy, in as safe a way as doable.

Sorry i dont understand the question can you rephase it?
