It really depends on your circuit. I can give just a generic answer for a simple circuit, simple being a voltage source and some resistances.
Ampere is a measurement of current. The ratio of voltage to current is resistance (V/I = R or V=IR is a more typical notation).
So your question starts with V = 12 and asks how to lower I. I am going to assume V is a constant source, so to lower I all we need to do is increase R. Once we increase R, I will automatically decrease so that the relationship V = IR is held constant. So first determine what you want your I to be, and then add resistors in parallel or series in order to get an R that keeps the voltage constant. or, to put it another way: The current, or Amperage, or the quantity of Amperes, flowing in any simple electrical circuit (at any given voltage) may be lowered or decreased by increasing the resistance in the circuit according to Ohm's law: V = IR, or in this case, its equivalent I = V/R The resistance may be increased, logically enough, by adding a resistor, a device with less than perfect conductance, originally made from carbon or thin wire. Or, if there is a variable resistor (a Rheostat) in the circuit, it may be adjusted to increase its resistance. Electronic devices, such as transistors or vacuum tubes, can also provide variable resistance in a circuit.
The battery voltage on a PT Cruiser is typically 12 volts.
To change the voltage of a 12-volt battery to a 6-volt output, you can use a voltage regulator or a step-down transformer. A voltage regulator will reduce the voltage to the desired 6 volts, while a step-down transformer will step down the voltage from 12 volts to 6 volts. Both options will help you achieve a stable 6-volt output.
To find the amperage, you can use the formula: Amps = Watts / Volts. In this case, with 72 Watts and 12 Volts, you would have 6 amps of current.
Yes, series the two batteries to produce 12 volts. Tap off of the two end terminals for the 12 volts. Tap off of the series jumper for the 6 volts of one of the batteries. The two 6 volt batteries can not be paralleled in this connection as they will short out.
Yes, when converting from a 6-volt system to a 12-volt system in a vehicle, you typically need to replace the coil with one that is compatible with 12 volts. This is because a coil designed for a 6-volt system may not be able to handle the higher voltage and could lead to issues with the ignition system.
12 volts
If the voltage is AC a transformer can be used.
It is 12 volts.
No. 12 volts peak to peak would be 6 in the positive polarity and 6 negative polarity. Simply saying 12 volts AC would be 12 volts in each polarity or 24 volts peak to peak

Automobile batteries today are all 12 volt. Most auto manufacutures switched from 6 volts to 12 volts in the 50s.
