Answer:
Advantages of Digital Multimeters:
1)They are more accurate than analog multimeters.
2)They reduce reading and interpolation errors.
3)The 'auto-polarity' function can prevent problems from connecting the meter to a test circuit with the wrong polarity.
4)Parallax errors are eliminated.
I hope this helps.
Answer:
This is true but an Engineer is much more than that. They are the professionals of engineering, who do the invention, analyze, design and test complex systems, machines, structures, machines for fulfilling the functional objectives gadgets as well as the requirements while taking into consideration the limitations that come up due to practicality, safety, regulations, and cost.
Explanation:
Please check the answer section.
Mobile phones transmit and receive signals using electromagnetic waves, that is, wireless signal are electromagnetic waves which can travel through a vacuum, they do not need a medium or matter.
<h3>What are electromagnetic waves?</h3>
They are generated by electrical and magnetic particles moving at the same time (oscillating).
<h3>Characteristics of electromagnetic waves</h3>
- Network waves are electromagnetic waves.
- A mobile phone has coverage when it receives electromagnetic waves from at least one base station.
- They do not necessarily require a material medium for their propagation.
Therefore, we can conclude that electromagnetic waves are those that do not need a material medium to propagate and include, among others, radio, television and telephone waves.
