What else can I help you with?
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
What is an electric current flowing in only one direction?
An electric current flowing in only one direction is called direct current (DC). This type of current has a constant flow of electrons in one direction from the negative to the positive terminal of a power source, such as a battery.
Where would you find a series circuit?
The main advantage of a series circuits comes from the fact that when you add a power source, its voltage just gets added to voltage of the circuit. This increase in voltage allows you to easily increase the power going to any electrical device just by adding more sources of voltage. In addition, since current is constant across a series circuit, if you have a collection of devices that all require the same or closely related current, a series circuit instantly gets you there. Finally, on a more economical note, since you only need to wire one loop in series (as opposed to multiple in parallel) you will end up using less wire and spending less on materials to create your circuit. However, if you plan on powering multiple devices at once with the ability to remove any of them at any time or want them to have the same voltage and not the same current, you will have little choice but to concede and use a parallel circuit structure instead.
How can you do the 12 volts reduce to 6 volts?
It really depends on your circuit. I can give just a generic answer for a simple circuit, simple being a voltage source and some resistances. Ampere is a measurement of current. The ratio of voltage to current is resistance (V/I = R or V=IR is a more typical notation). So your question starts with V = 12 and asks how to lower I. I am going to assume V is a constant source, so to lower I all we need to do is increase R. Once we increase R, I will automatically decrease so that the relationship V = IR is held constant. So first determine what you want your I to be, and then add resistors in parallel or series in order to get an R that keeps the voltage constant. or, to put it another way: The current, or Amperage, or the quantity of Amperes, flowing in any simple electrical circuit (at any given voltage) may be lowered or decreased by increasing the resistance in the circuit according to Ohm's law: V = IR, or in this case, its equivalent I = V/R The resistance may be increased, logically enough, by adding a resistor, a device with less than perfect conductance, originally made from carbon or thin wire. Or, if there is a variable resistor (a Rheostat) in the circuit, it may be adjusted to increase its resistance. Electronic devices, such as transistors or vacuum tubes, can also provide variable resistance in a circuit.
What type of circuit would be used in a battery operated torch?
A simple series circuit is typically used in a battery-operated torch. This circuit allows for the flow of current from the battery through the light bulb, providing illumination. The components are connected in a loop, where the positive terminal of the battery is connected to the light bulb and then back to the negative terminal of the battery.
As the total resistance is reduced in a simple electrical circuit the current flow will?
increase

What is a circuit that only has one loop of wire?
A simple circuit that has only one loop of wire is a series circuit. In a series circuit, the components are connected in a single path, forming a closed loop for the current to flow through. If one component fails, the entire circuit will be broken.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
What si th difference between a series and parallel circuit?
The primary difference between a series and a parallel circuit is how many pathways the current has to travel in. Let's look at both of them and see what's up. In a simple series circuit, there is only one path for current. The current must flow through every component in the circuit.
Does a battery operated toy have a parallel circuit?
Yes, a battery operated toy has a parallel circuit - the battery is in parallel with the toy. In fact, this is true for any system where there is a single equivalent source and a single equivalent load. While it is true that this is also a series circuit, by Kirchoff's current and voltage laws a simple series circuit is also a simple parallel circuit.
In a simple circuit is a battery in series or parallel with the resistor?
In series.
In a series circuit How does the voltage from a battery compare to the voltages on each load?
The sum of the currents through the branches of a simple parallel circuit is the current that flows through the voltage source.Kirchoff's current law: The signed sum of the currents in a series circuit is zero. The sum of the currents in the branches represents one effective path, which is in series with the voltage source, so the two effective currents must be the same.
Does adding resistors in series increase or decrease the overall resistance of a circuit?
Resistance in series adds together. two 100 ohm resistors in series are equivalent to one 200 ohm resistor. to make an equation out of it ( even though it is simple) you can say: Rtotal=R1+R2+R3...+Rn
What happens to current in a simple circuit as potential difference is increased?
depends on the simple circuit. please describe it.
What is an electric current flowing in only one direction?
An electric current flowing in only one direction is called direct current (DC). This type of current has a constant flow of electrons in one direction from the negative to the positive terminal of a power source, such as a battery.
