In this video I want to look deeper into nodes and antinodes in a transmitter receiver situation. I also look at the influence on a reference point voltage wise. Next video will be referenced point magnetically wise.
Things I learned:
1) Voltage wise in transmitter we go from node (point of least amplitude) on one side of the coil to antinode (point of maximum amplitude) on other side of coil.
2) Current wise in transmitter we go from antinode on one side to node in middle of coil and back to antinode on other side of coil. Polarity of the antinodes is invers in reference to each other.
= This means that current isn't always where voltage is.
3) Voltage wise on ungrounded receiver we go from antinode on one side to node in middle and back to antinode on other side.
4) Current wise on ungrounded receiver we go also from antinode on one side to node in the middle and back to antinode on other side.
5) Earth grounding receiver will lead to higher voltage, but also lower current
6) Best position for influence on reference point voltage wise in a 2 coil system (sender-receiver) was in the middle & Earth grounded.
7) Best position for influence on reference point current wise (magnetically) in a 2 coil system (sender-receiver) was close to reference point & NOT Earth grounded.
