When placed in series a coil and capacitor resonate at a frequency of 2251Hz and when placed in parallel they resonate at a frequency of 2228Hz. At parallel resonance it is also found that a current of 5mA flows from the supply when the supply voltage is 25V r.m.s. Determine the value of the...

Thanks again CEL, I thought i was losing it.

Hi Cel Thanks for your reply. I've been looking at this question for a few days now and I still get a negative sign at latter end of the expression. Here's how I've got there. Question A voltage amplifier ideally shouldm have the input-output realationship of v(0) = 100 v(i) but...

Hi there, I think I've got the answer. Just need it checking! Vo = 0.1 + 0.98sin(1600 pi t) - 0.1cos (3200 pi t) Thanks for any reply.
