Let's say you have a basic series circuit with a battery power source that has 12 volts. You also have a load of some sort with 3 ohms of resistance. Therefore you'll have 4 amps of current throughout the circuit. Is it possible to add some item within or along the circuit (and before the load) the could increase the amps on the output side of that item (whatever it is)? In my question, the current coming from the power source is 4 amps, then after it passes through that item (with some unknown ohms of resistance), it increases to 5 amps (the input amps stays at 4 amps), and then stays 5 amps through the rest of the circuit. Is this possible? If it is possible, what would happen to voltage and what would the ohms likely be? If not can you briefly explain why?
