If headlight uses 150 w and the car battery produces 12 v what is the current in the circuit?

As w = v * a
current = 150 * v * a / (12 * v) = 150/12 * v * a / v = 150/12 * a = 12.5 * a = 12.5a

Describe how a battery can create a current in a conducting wire?
The battery produces a voltage; if a conducting wire - or any circuit for that matter - is connected, a current will flow according to Ohm's Law, that is, the current is calculated as voltage / resistance.
Why does a circuit stop working when you remove the battery?
The battery is the power source of the circuit. It supplies current to the circuit and the circuit is simply a path for the current to follow. When you remove the current (battery), the path still exists but there is no current going through it.
A 6-volt battery produces a current of 0.5 amps what is the power in the circuit?
The formula you are looking for is W = I x E.
What part of an electrical cicuit produces the electric current?
Either the cell e.g. a battery, if one is included in the circuit. Or a generator such as a dynamo
If the headlight on your mom and car has a resistance of 32 ohms and the car battery put out 12v what is the current through the headlight circuit?
well first you going to divide 32 by 12 and get 2. 66 repeat amps.

Is a car battery a circuit?
Hi, there. A battery is a power supply, a source of potential difference which drives current. In itself, a battery is not a circuit, but if you attach it to a load (a resistance), then a current will form and a circuit is made!
What type of current will a circuit that involves a battery and electrons traveling in one direction have?
a battery always produces a direct current.the electrons always travel from the negetiove to the positive terminal.But the direction of the current is the opposite that is from the positive to the negetive terminal.
Does a battery supply the electrons in an electric circuit?
No, is it incorrect to say that a battery produces the charges that circulate in a circuit. Some might suggest that a battery is a current source, but the battery should most properly be considered a voltage source. It generates the electromotive force (emf or voltage) that causes charges to move. (It does this through electrochemical reactions.) The charges that circulate in a circuit (which might be termed the current flow) are already in the conductor and components. All the battery does is produce the voltage (the force) to move charges. Let's look at current flow and see why things might be best looked at in the manner we've stated.Note that the way a battery moves charges is to "inject" an electron into the circuit where it is tied to the negative terminal of that battery. The electron causes one electron in the circuit at the terminal to "move over" and that will cause another electron to "move over" and so on. This will continue until the "last electron" in the circuit at the positive terminal of the battery leaves the circuit and "goes into" the battery. Current flow in the circuit is like musical chairs with electrons everywhere in the circuit "moving over a space" to cause the current flow.Having gone through all that, it should be easier to see why a battery probably should not be considered the producer of charges that circulate in a circuit. Rather, the battery is the source of the voltage that drives the charges (the current) in the circuit.
Is it true that a battery produces alternating current?
No. A battery produces DC, or Direct Current.
What is current in the battery called?
A battery contains a charge of electrons. When these electrons leave the battery and travel through a circuit that is described as current.
If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
