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.

An electric DC circuit is attached to a 12-volt battery and has a 3-ohm resistor in it find the current flowing through the circuit?
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.)

What is an complete circuit?
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.
Which creates a potential difference in an electric circuit?
A battery can cause that; also, energy provided from some external source - as you would get in your electric outlet.
An electric dc circuit is attached to a 12 volt battery and has a 3ohm resistor in it What is the current flowing through the circuit?
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.
What is the current flowing through a 12volt battery that has 3ohm resistor that is attached to a dc circuit?
I=v/r, then 12/30=4/10=0.4amp
What device creates a potential difference in an electric circuit?

In a simple circuit is a battery in series or parallel with the resistor?
In series.
What is the condition that limits the flow of electrons in an electric circuit is called?
what is all conditions which limit the flow of electrons in an electric circuit? A resistor
What is meany by resistor?
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.
What is the source of the electric circuit?
Battery
What does a resistor do in an electric circuit?
Limits current flow and drops voltage.
What is the function of resistor in electric circuit?
the function of a resister is to lower the voltage.
What would be a basic electical circuit?
a battery and a resistor connected together.
Which device controls the flow of electrons in an electric circuit?
Flow of electricity in a circuit is controlled by using 'resistor'.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
