Both conductor capacitor and inductor shown red is inductor and blue is capacitor. |
Change decrease frequency by 10 hertz inductance go down for inductor circuit. and Result of changing 60-10hz amplitude goes down by equation 1/2 XL=1/2/pi/f |
10 hertz below amplitude go up
10 hertz below amplitude go up |
Inductor 16 hertz
Transformer experiment
Outside of Wall Wart |
A wall wart(AC adapter) was passed around the class for examination of eddy currents (undesired) and electrodynamical transformations of energy. A transformer is made of two inductors linked together by an iron core(best if laminated). The iron core manipulates the magnetic flux from one inductor to the other. Eddy currents are the undesired currents created by the changing magnetic field. The Eddy currents increases energy lost and the solution to this is to laminate the plates of the iron core because laminated layer reduces the size of the induced loop and therefore reduces the amount of energy lost.
List of equations relative to impedance(R) and phase angles with Resistor, Inductor, and capacitor: with RL, RC, RLC circuit. |
Transformer is made up 2 conductors made up of 2 conductors iron cores
Hook it up alternating voltage->current -> field
coil reversing 60hz and magnetic field up and down
Magnetize iron core: turn it to U magnet
