If the bulbs are in a series circuit the voltage drops at each bulb drops as additional bulbs are added.
In a parallel circuit the voltage is constant no matter how many bulbs are added.

∙ 12y agoThe resistance decreases if you add more resistors in parallel.
The total resistance R of n resistors R1, R2, ..., Rn in parallel is given by the formula:
1/R = 1/R1 + 1/R2 + ... + 1/Rn
and therefore, since resistance is always positive, adding an extra term to this series will always increase the total conductance 1/R. It follows that adding an extra resistor to the network will always decrease the total resistance.

When a load is connected, and a load current flows, the terminal voltage falls because its internal voltage drop increases. So, the answer is that if the resistance of a load increases, the load current falls, the supply's internal voltage drop falls, and its terminal voltage increases.

Does more current flow through a parallel circuit than a series circuit?
Two resistors in parallel are equivalent to a single component with a lower resistance than either of the pair. Two resistors in series are equivalent to a single component with a resistance equal to the sum of the pair, therefore a higher resistance. For a given potential difference, more current in total will flow through two resistors in parallel than through the same resistors in series.
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 a current circuit?
A current circuit refers to a closed path through which electric current flows. It is formed by connecting various electrical components, such as resistors, capacitors, and inductors, with conducting wires. The current circuit allows the flow of electric charges, usually in the form of electrons, from the power source to the load.
What happens when a battery is hooked up to an open circuit?
nothings because they is no wire connected to the circuit so no current can flow through
What happens to a circuit if the resistances is increased?
The voltage drop across each resistance will go up, and the current through the circuit will go down.
What is true of a series circuit that has two resistors?
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
Does the current remains the same in a series circuit despite the different values if the resistors in the circuit?
current in series depends on values of resistors. more resistance less current will flow through and viceversa
How do resistors affect a circuit?
It reduces the current. As the current travels through the resitors it has some current that is left in the resistor. And
When two resistors are conected in parallel what happens to the current as it passes through the circuit?
According to Kirchhoff's Current Law, the sum of the individual branch currents must be equal to the total current before (and after) it branches.
Differentiate parallel circuit and siries circuit?
If two circuit elements (e.g., two resistors) are in series (a series circuit), the current has to pass first through one, then through the other. If they are in parallel, the current has a choice, through which of the elements it passes.
The circuit is a series circuit because?
The same current flows through both light bulbs.If one of the resistors run out of power,the whole circuit shuts down
Does more current flow through a parallel circuit than a series circuit?
Two resistors in parallel are equivalent to a single component with a lower resistance than either of the pair. Two resistors in series are equivalent to a single component with a resistance equal to the sum of the pair, therefore a higher resistance. For a given potential difference, more current in total will flow through two resistors in parallel than through the same resistors in series.
What happens as a current flows through a parallel circuit?
if the circuit is a series circuit (all loads wired in a single line , one after the other ) then the current will be the same in any part of the circuit . if there are several different paths for the current to take , then each path will carry a different percentage of the total current . when each of these different current values are added together , they will equal the total supplied current.
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 is the current of a circuit that has two 5-ohm resistors and a 12 V battery?
If the two 5 ohm resistors were in series, then the current would be 1.2 amperes. If they were in parallel, then the current would be 4.8 amperes. Ohm's Law: Current = Voltage divided by Resistance RSeries = Summation1toN RN RPARALLEL = 1 / Summation1toN (1 / RN)
