    Solving Series Transformers Problem with Lumped Resistance

    Cannot be answered without knowing transformer efficiency (function of frequency, windings, core material). An average current would be expected if the two transformers were magnetically coupled and behaving as one large transformer. Cheesy E-lams at 50-60Hz have a huge field...

    Slippery finger pushing on a large drum head.

    Concentric waves will form in the drumhead, the nature of the wave being a result of the excitation velocity, the drumhead material and fluid (presumably air). The result is that the wave will transfer energy to the fluid where frequency is a function of wave diameter. In other words, higher...
