I have built an Ohm meter using voltage divide. It works well and as expected the resistor get hot. (0.5W carbon film)
Question is what power value would be best for the resistor to keep the heat generated low?
The circuit is for my vehicle LPG (aka CNC, Propane) tank gauge that reads 0-95 Ohm and is powered up when driving and acts like a fuel gauge.
Also is there a better way to measure resistance?
