What item could be put into a circuit that is a resistor?

Answer 1

Gee...Your hand will do nicely. Any resistor in a pinch.

Answer 2

I am not exactly sure what you are asking...

Do you mean... "what item could be put into a circuit that could replace a resistor?"

In that case, we sometimes use a transistor that is connected such that it behaves like a resistor when doing integrated circuit design. When building large scale integrated circuits on a single piece of semiconductor material, resistors are quite difficult to manufacture accurately. Transistors, on the other hand, are quite easy and take up relatively little space.

And of course there are many other devices that have some resistance associated with them. Multi-meters, for example, have a certain amount of resistance that can alter your measurements slightly.

Answer 3

The general answer is a "load" or a resistive element..this is anything that gobbles up current and dissipates it as energy, usually heat, ...for example lights, motors, tv's, speakers....remember in dc circuits v=i*r ...
low r is high i,,vice versa

Answer 4

A speaker works

Answer 5

in dc circuits, a coil will work
