For a.c. you can use a transformer; for d.c. you can use a voltage divider resistor network.
You can use a circuit that uses a transistor to regulate the voltage down to 8v by adding resistance under control of a reference zener diode.
There are dedicated voltage regulators with three legs like a transistor, the 7808.
Other circuits use an inverter. Where the 12v is chopped up and fed via a computer controlled transistor, recified and stored in a capacitor for output.
It all depends on how much current you want to use. The voltage divider will only give you a small current, usually for reference only.
Adding resistance (via transistor) will produce large amounts of heat as the extra voltage is wasted.

How do you convert a 220volts to 12 amp output?
Volts cannot be converted to amps. If you mean convert 220v to 12 volts output, then you need a 220v to 12 v step down transformer with the VA or watt rating you require.
How do you convert 5 volts into 12 volts?
If it is AC voltages you need to convert, you need to find a transformer to do this job. Without knowing the application it is hard to guess what you are trying to do.
Convert the following 5 kilo volts to volts?
5000 volts
How do you Convert volts?
To what?
What does 1.5 watts equal to amp using 12 volts?
volts times amps equal watts. So 12 volts times ? amp equals 1.5 watts. The current is 1.5/12 amps, which is 1/8 amp.
What is the formula to convert 240 volt to 12 volts?
If it is AC then you don't need a formula, you just need a transformer.
How do you convert 12 volt trailer lights to 24 volts?
Change the trailer light bulbs to 24 volts and supply a 24 volt source to power them, in that order.
Is a marine battery 12 volts or 6 volts?
12 volts
What is the current through a 4 and 8 ohm resister in sereis with 12 volts across both resisters?
Total resistance (thevinen resistance) = 4 + 8 Total voltage = 12 volts. Ohms law: I = V / R Therefore I = 12/12 = 1 amp.
Convert between fractions and decimals 8 over 12?
8/12 = 0.666 (repeating decimal)
Is there a converter that will turn car DC to use on microwave oven?
Yep. It is called an inverter to convert 12 volts to 110 volts AC. Get one that will supply the amp needed for the microwave.
How can you convert amperes in to volts?
Amperes does not convert into volts they are two different values. Become familiar with the following formula and look at the relationships between the values. Volts = Amps x Resistance, Amps = Volts / Resistance and Resistance = Volts / Amps.
