maybe some of you analog experts can help me. i got a data sheet for a (www.cui.com/product/resource/cmt-8530s-smt.pdf) MAGNETIC BUZZER TRANSDUCER, it's just a pz disc and a coil housed in a resonant casing. WTF? LCOIL= ?, CDISC = ?.

It says that the current consumption is 90 mA. that's with a square wave, 50% duty cycle, at 2730Hz. and a voltage of 0 - 3.6

the RCOIL = 16ohms.

but i have to drive it at different voltages and and duty cycles. how to calculate the current for arbitrary V and duty cycle?

i'm assuming it's a standard parallel L and C circuit.

is it possible with so little information?
