In this photo Mick used a glass of water to show us how water is a good resistor but, can also be a very good conductor if salt is added. By adding salt it knocks hydrogen loose and the plating off the roach grips turning the water a nasty beer color.
Mick is Showing us how A/C current is made in an Alternator. Through positive and negative pieces on the gear. Changing polarity of magnets. Iron core in a magnet intensifies it by 2500x is also called a ARMATURE (chunk of iron in the middle) move in a magnetic field.
I always thought dielectric grease was used to help with bad electrical connections. We were told in class they're for protecting electrical connections. Is it used to improve a connection too?
Hard to read your black letters on back ground. Good info.
ReplyDelete2/3 Good work, Michael. I like the pictures you chose to share and your captions indicate that you understand the material. For next time, I would like you to include more reflection about what you learned. How/why is the material important to you? Was anything difficult for you? If so, why was it difficult? Were you able to connect what you learned this week to other parts of the course? Please see me if you need further clarification or help with this. :)
