![P=IV & V=IR Question - Mike Holt's Forum]()
forums.mikeholt.comnoobie question, but wondering if someone can clarify this for me. i know according to Ohms law V =IR that the voltage and current are directly proportional that if one goes up the other does as well. but when we use the power equation P=IV it is the oppo瀏覽：1308 -
![V=IR, P=IV=I^2R=V^2/R, signal energy confusion.]()
sci.physics.narkive.comV=IR, P=IV=I^2R=V^2/R, signal energy confusion. Steve 2007-01-23 11:26:02 UTC I'm finding myself confused by signal energy for a signal V(t) and P=V^2/R as derived by Ohm's Law. Given a fixed load R and the potential energy of a charge q don't we have ...瀏覽：1461
