The total current decreases.
According to the Ohm's law the current & the resistance are inversely proportional so when we put a load in series with the existing load, the resistance of the circuit increases therefor the current decreases.

What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
When do you use Parallel circuit?
A parallel circuit is used when the current through several components needs to be independent of each other. The simplest example is that of lights in a home. The lights with their switches are wired in parallel. Turning on one light does not affect any others and similarly, turning a light off does not turn off any others. Each light is supplied with the same voltage which does not change even if other lights are turned on or off. A series circuit is one where the current flows through one component and then through a second component and so on. If the current flow through one component is changed, it is also changed in all the others in the series circuit. A string of Christmas lights is a good example. Removing one bulb from the string of lights will stop all the others operating because there is no current flowing through any of them.
When 5 coulombs of charge per second pass a point in an electric circuit the electric current in that part of the circuit is?
2 amperes
What is the difference between the inrush current and the fault current?
Magnetizing inrush current has bigger 2nd harmonics compare to short circuit current. the second harmonics content is about >60% of fundamental harmonic. magnetizing inrush current happened when we energised the transformer, and short circuit current happened if there is a short circuit between different alive phase.
What components compose the excitation current of a transformer. How are they modeled in the transformer 's equivalent circuit?
The magnetization current can be broken-down into two components: the first is in phase with the supply voltage and is responsible for the losses, whereas the second component lags the supply voltage by 90 degrees and in responsible for the magnetic field.
Consider two identical resistors wired in series one behind the other If there is an electric current through the combination the current in the second resistor is?
Two resistors wired in series (no mater if they have the same resistor value or not) will always have the same amount of current flowing through them. Therefore, the current flowing through the second resistor will be equal to the current flowing through the first one. The current through every component in a series circuit is the same. The voltage across every component in a parallel circuit is the same.
What is the difference between altenating current and direct current?
The current (or electrons if you will {but thought of as flowing in the opposite direction} in a DC circuit flows only in one direction. In an AC circuit the current periodically flows in the opposite direction (in the US this usually happens 120 times a second, so 60 cycles per second.)
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
When you add a second battery to a series circuit what happens?
Adding a seound battery to a series circuit will increase the voltage, and require less current to keep the lights (if there are any on) as bright. Say you have a 6v battery, then you add another 6v battery. the voltage of the circuit would be 12v

What happens if you use an ac circuit breaker instead of dc breaker?
A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.
If you unscrewed the second bulb in the parallel circuit when it was on what happens to the first?
Nothing. That's why it's a parallel circuit. If it was a series circuit, then the first bulb would go out.
What is alternated current?
That refers to a current in which the direction of flow changes continuously. In household current, this usually happens at 50 or 60 cycles per second (depending on the country), but the definition of alternating current can include just about any other frequency, as well.
