What is the current through the headlight circuit if the headlight on your mom's car has a resistance of 32 ohms and the car battery put out 12V?

well first you going to divide 32 by 12 and get 2. 66 repeat amps.

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).
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.

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 is lost volts?
A battery is rated to supply a certain number of volts. However, it actually supplies less, because they are "lost" as the current has to get out of the battery in the first place.(The battery has internal resistance)The amount of lost volts depends on the current being drawn:The less resistance a circuit has, the more current is drawn, because it's easier to flow.Example:If the circuit has little resistance, it draws a large current and the battery's internal resistance causes more lost volts.If the circuit has high resistance, it draws a small current and there are fewer lost volts.This is why when you short-circuit a battery (give it hardly any resistance to go through) it heats up and may explode. A large current is drawn and all the volts are used by the battery's internal resistance.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
If a series circuit has a 12 v battery what is the current flow?
You'd need to know either the resistance or the wattage of the circuit. Ohm's Law: Current = Voltage divided by resistance or Current = Power divided by Voltage
If a parallel circuit shorts at the battery will the entire circuit short out too?
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

How much current is in a circuit that includes a 9-volt battery and a bulb with a resistance of 12 ohms?
Current = voltage/resistance If those are the only components in the circuit, then Current = 9/12 = 0.75 Ampere = 750 mA
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
How much available current in a 9 volt battery?
It depends on the resistance of the circuit, as V=IR, so I=V/R (V=Voltage, I=Current, R=Resistance)
