Timer0 Interruption xc8
Personally I prefer never to use the "simplified" macros provided by Microchip. They hide just what is going on from you and you never learn what you're really doing with the hardware.
I notice you a …

What is __bit in the XC8 C compiler?
bit and __bit are exactly the same, except for the level of compatibility:
If the xc8 flag --STRICT is used, the bit keyword becomes unavailable, but you can use the __bit keyword. … The MPLAB XC8 C compiler supports various special keywords (for example the
persistent type qualifier). …

extern and the XC8 C compiler
extern is largely obsolete for functions in other CUs in many of the smaller simpler compilers. If a symbol isn't found locally it will be searched for in other CUs and libraries. You provide a func …

Ohmmeter not working as expected
You are joining your HIGH and LOW byte values together wrong:
unsigned int adc = ((ADRESH<<2) | ADRESL);
You have a 10-bit result, 2 bits in ADRESH and 8 bits in ADRESL.
Say the two values are …
