I googled Ohm Amplifier and got all the speaker links you might ever want.
so....I searched thru some threads on here and found some that got near what I was looking for, but I couldn't find a clear solution,
so..... I registered and thought I'd ask outright.
I have a level gauge that shows full at 2-5ohm and empty at 105-110ohm.
I have a level sender that gives 0ohm at full and 70ohm at empty.
I imagine I could piggy back a resistor on the sender and get the gauge to read correctly at one end, but it would come up half short or way long on the other.
Is there a way to amplify the resistance dynamically so I can be accurate on both ends?
if my math is correct, i'd need a flat 3ohm push at 0 (sender output), with a .5ohm per ohm linear rise.
full: 0+3+(0x.5) = 3
empty: 70+3+(70x.5) = 108
Thanks for any help!
Hope I'm not coming off as a complete newb.....
