Why does voltage reading increase the greater the resistance load?
I'm new to electronics. So basically I already understand Ohm's law and the math behind why this is the case. What I don't get is the idea behind it.
Shouldn't the greater the load resistance be, the ...

Fuel sender - need something to convert ohms to volts?
I need to connect a cars fuel sender(ohms) to a analog input on a GPS tracker (volts)
Here's the catch, in our tests most fuel senders we worked with seem to send the data as ohms/resistance
However,...
