For Roy Lewallen et al: Re Older Post On My db Question

"Nothing like Vrms times Irms through it is it?" Yes it is. Sorry I fat fingered (E=1ampere). It is I=1 ampere. 1 ampere times the 85 volts dropped across an 85-ohm resistor by 1 ampere = 85 watts, same as 1x1x85=85, or 85x85/85=85. All methods of calculation must give the same answer, and they do if you don`t make a mistake. Best regards, Richard Harrison, KB5WZI |
