HI...my name's Vince and i'm an ET student. We were given a homework and I was researching through "Ask Jeeves" and i saw a link where you answered someone's question for their project. My question is this: Why is it that using measurement of a circuit's voltage with a voltmeter and its current with an ammeter does not provide the necessary info to find the actual power dissipated by the circuit? And is the tuned circuit of a receiver typically series or parallel LC circuit? Hope you can provide me the info i need....i'd really appreciate it...thanks so much --------------------------------- Do you Yahoo!? Protect your identity with Yahoo!
