Use the equation, V= IR from Ohm's Law V is the voltage, I is the current, and R is the resistance in ohms So then, solve the equation for I (the current) and you get I=V/R. Then just plug in the values... I= 12/3, which equals 4 A. (For current, it is measured in amperes, or just "A" as the unit.)
No, a battery is not a resistor. A battery provides electrical energy, while a resistor is a component that restricts the flow of current in a circuit.
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.
Adding a resistor to an electric circuit reduces the current flow by impeding the flow of electrons. The resistor increases the resistance in the circuit, which in turn decreases the amount of current that can pass through.
If the 3-ohm resistor is the ONLY thing in the circuit, then the current flowing through it is (12 volts)/(3 ohms) = 4 amperes. If there are other things in the circuit besides the resistor, then the current depends on all of them.
A resistor limits the flow of electric current in a circuit by providing resistance to the flow of electrons. This resistance reduces the amount of current that can pass through the circuit, helping to control the flow of electricity and prevent damage to components.
The current depends on the total effecvtive resistance of everything connectedacross the battery.If the resistor is the only component there, then the current is E/R = 12/3 = 4 amperes.

I=v/r, then 12/30=4/10=0.4amp

In series.
The type of circuit you are describing is known as a simple circuit. It consists of a power source (electric cell), a switch, a conductor (usually wire), and a resistor to control the flow of electric current.
a battery and a resistor connected together.
Battery
Resistor is a component of an electric circuit that resist the flow of direct or alternating electric current . It can also limit or divide the current, reduce the voltage, protect an electric circuit, or provide large amounts of heat or light.
Limits current flow and drops voltage.
the function of a resister is to lower the voltage.
