The unit for resistance is Ohm. When subjected to a potential difference of one volt, the SI unit of electrical resistance transmits a current of one ampere.
<h3>What is resistance?</h3>
It is an electrical circuit, that use to measure the resistance to current flow. The Greek letter omega is used to represent resistance in ohms. Georg Simon Ohm (1784-1854), a German physicist who researched the link between voltage, current, and resistance, is the name given to Ohms.
Thus, option C is correct.

The answer to this question is <span>Longitudinal Study
The main purpose of this type of study is to find out whether a certain variable will give different response if the time factor is change.
Examples of this time of study would be: a sudy to find out how long it need for a certain viruss to develop if it got injected since early age.</span>
A : oil
or B : timber
i think its timber though
