I'm sure you're right but I was wondering more along the line why a current amplifier can't be used to drive esl's?
U=RI and all...
Since I'm a no0b with the electronics bit there's a lot for me to learn.
However...
Since the stators aren't touching can there really be a current running through the circuit?
The definition for an electric field found in my physics book reads
E=x(V2-V1)/a
E being the electric field [V/m], V2 and V1 the electric potential [V] of the stators, a the distance [m] between the stators and x, well I'm not really sure what the x is doing there?
Please correct me if I make an error. It would appear the electricfield can exist without a current as long as there's a difference in electric potential.
If I remember things correctly it is the change in the electric field that's causing the charged diaphragm to move?
P=U^2/R
P being the power [W], U the Voltage [V] and R the resistance [omh]. In our case R isn't really R but Z. This would explain power needed by the esl.
Still I feel like I'm missing something really essential.
How could there not be a current? It really makes my head hurt.
Please, can someone explain this to me?
