I'll take a stab at this but since I don't actually use one, some of this information might be incorrect.
1. Place it inline with the + side
2. You attach your multimeter across the terminals of the resistor. Doing this, you will be measuring the voltage drop across the resistor and can calculate the current flowing through it by using Ohm's law, V=I*R. Since resistance is known and you are measuring the voltage across it, I=V/R. Using a 0.1 ohm resistor makes this a simple I=10*V. Other size resistors can be used, but you would ideally like to use a small one to minimize the voltage drop.
3. Buy a resistor based on the maximum current you plan on using. Since you buy resistors based on wattage, I would over-estimate the maximum voltage you plan on running a bit. 15Volts for LCD, 18 volts for standard. Use the formula P=I*I*R to calculate the power you will be passing through the resistor. For example, if anodizing at 10 amps with a 0.1 ohm resistor, P = 10*10*0.1 = 10 watts.
4. Yes, it's installed during the entire process.
Fibergeek, care to double-check my answers to ensure they're correct?
