Which describes the two parts of a measurement? a unit and a symbol a conversion factor and a number a symbol and a conversion f
wariber [46]
<h2>Right answer: a number and a unit</h2>

The measurement consists in <em>comparing a selected pattern with the object or phenomenon whose physical magnitude is going to be measured, to find out how many times the pattern is contained in that magnitude.</em> That is, it is about identifying or quantifying a particular characteristic or aspect of a particular object or construct.


Now, a well done measurement has two parts:

-The number gives us information about the quantity of the measurement, or in other words, the magnitude of the measurement and its precision.  

-The units gives us information about the property that is being measured. This is quite important, because a measurement or result with no units is useless.

Note the units may be expressed with letter or symbols, depending on what we are measuring.

alexandr402 [8]

Answer:

Explanation:

Voltage and current in resistors

A graph of current against potential difference shows you how the current flowing through a component varies with the potential difference across it. The current flowing through a resistor at a constant temperature is directly proportional to the potential difference across it.
