To run 12v dc things in a car the battery outputs 12v regularly but it can go as high as 14.4 when the engine is running I need a circuit to regulate this at say 12v 10 amps to prevent over voltage?

the alternator is what puts out the 14.4 volts. if you wish to figure out the circuit use the formula A*R=V so you take the voltage 12 divide by the amp 12 and you get 1.2 as the resistance. so in your circuit, the max allowable load is 1.2 ohms.

What is a simple circuit with one or two inputs and one output?
The following are definitely examples of a simple circuit:-A resistor hooked across a battery-A lit bulbThe following might be examples of a simple circuit:-A Logic gate has one or more inputs and one or more outputs but is not necessarily a simple circuit within the chip containing it.
What is combinational circuits in computer architecture?
combinational circuit is depend only on inputs,like sequential circuits its not depend on previous outputs.
You will lose circuit protection if you use which two ways as outputs?
1 and 2
Similarities between combinational logic circuit and sequential logic circuit?
both combinational and sequential circuits have two inputs and outputs..!
Can you charge a 5 volt battery with a car charger?
No, an automobile battery charger outputs 12 Volts. This is far too many volts to charge a 5 Volt battery. You would destroy the 5 Volt battery with this charger.
Will a dc to dc charger charges a battery bank faster than an ac to dc charger?
No. The speed at which the charger will charge the battery is determined by how many amps the charger outputs.
What is the component for a battery cell?
A battery is very simple. A single cell is made of two dissimilar metals in an acid. When several cells are stacked together we get batteries with different power outputs.
What does the terminology - load - mean in reference to a residential wiring connection?
In basic the load is commonly referred to in relation to the outputs required by that circuit. i.e. How many x wattage lamps will, as a maximum be on a circuit. therefore the term 'load' may refer to the power consumed by a circuit
All circuit boards contain microchips?
Circuit board is the name for the place / board that parts are put on to to make a circuit. All circuit do not have to have a microchip but that board will not do anything fancy. A speaker crossover for example is the only thing I can think of. All micro chips will need a circuit board to connect power, inputs, outputs, or just to mount into a package.
Is base emitter circuit and common base amplifier same?
No the base emitter circuit is not the same as a common base circuit. The three BJT circuits all have the base emitter circuit. Wheter each terminal is common to both inputs and outputs of the circuit determines the type of transistor configuration.Henry Lee Everson PE;229-560-9769
WHAT IS IC 4017?
4017 IC is a counter, divider integrated circuit. It is a decade counter that has 10 different decode outputs and is commonly called a CMOS.
Will a 12 volt dc power requirement work on a AA battery?
No, not on 1 AA battery which only outputs 1.5 volts. Connect 8 AA batteries together in Series and you will have 12 volts.
