How many amps will you get on a 9 volt battery with a 100 ohm resistor and a 100 ohm resistor and a 470 ohm resistor?

You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.
