As more lamps are put into a series circuit what happens to the overall current in the circuit?

The more lamps you add, the dimmer each would become. The brightness would be the same for each lamp -providing they are all the same wattage. If one of the lamps wasn't working, then none of them would work. If the wattage of the lamps varied, the brightest lamps would be those with the lower wattage rating (yes, this is not a mistake!).
Lamps in series can be dangerous if one isn't working, because the full circuit voltage would appear across the open terminal.

∙ 12y agoEach lamp becomes dimmer as the voltage across each is reduced though the current stays the same. If there were 20 lamps in a 240 volt series circuit the voltage across would be 240/20=12volts if they were identical lamps. If you added 4 more then the voltage across each would be 240/24=10 volts, thus each would be less bright.
CommentThe current doesn't remain the same. It reduces in value.

What happens to current in a series circuit?
the current in series will be same..
What happens to the amount of current in a series circuit as the number of batteries increase?
it increases
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is special about electric current in a series circuit?
In a series circuit the current remains the same throughout the circuit. This is not the case for parallel circuits.
What happens to current in a series circuit?
the current in series will be same..
What happens to the current in the other lights if one light burns out in a series circuit?
It depends what is the outcome of burning. If that light has created open circuit, circuit will break and there will not be any current. But if there is short circuit means overall resistance is decreased. Thus current will increase. Besides overall brightness will also increase. Thus, if in a series lesser the number of bulbs more will be brightness.
What happens to the current in the series circuit?
current remains same in series while divide itself in parallel circuit
What happens if the track of the current is broken in a series circuit?
In a series circuit, if the current is broken the flow of all electricity stops.
What happens in a series circuit if a light blows?
The circuit current is interrupted and all the lights will go out.
What happens to the current in a circuit when one bulb is replaced by two bulbs in series?
current in series always stays the same
What happens to the amount of current in a series circuit as the number of batteries increases?
it increases

If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What happens to the current in circuit as the resistance increases?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
What happens to the total impedance of a series RC ciRCuit as the frequency is increased?
when the frequency is increased the total impedance of a series RC circuit is decrease.
In a circuit the current is the same everywhere?
By Kirchoff's current law, a series circuit has the same current everywhere.
