Day18

Oscilloscope and Mystery Box:

In this class time, AC/DC and other components of the oscilloscope were studied, and more and more familiar of  the oscilloscope is learned for future labs. All observations are made on the whiteboard photos below.

Mystery box:

After knowing the property of AC and DC and other components of the oscilloscope, we are going to measure a mystery box. This is how a mystery box looks like.

 Using the oscilloscope, we can find the frequency, time and voltage. 
                                   The value makes sense.
