The voltage between the ends of the circuit doesn't change ... that's where the
power source is connected. But when you add more items in a series circuit, the
voltage across each item changes.
The individual voltages across each item in the series circuit always add up to
the voltage of the power source. So in general, if you add more items, the voltage
across each of the original ones must drop somewhat.

∙ 14y agoA: voltage is a force that causes current to flow therefore if the voltage source is fixed the voltage will remain the same with the same load whether is series or parallel. However in a series circuit all voltage drops will have to equal to the source and the voltage drop across each impedance will add up to match the source.

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
The applied voltage in a circuit equals the sum of the circuits individual what?
For a series circuit, the applied voltage equals the sum of the voltage drops
How is total resistance in a series circuit determined?
Series circuit: The total voltage is the sum of the voltage on each component. The total resistance is equal to the sum of the resistance on each component. The total current is equal in every component.
State two rules for the voltage and current in a series circuit?
Kirchoff's voltage law and Kirchoff's current law
What is the relationship between voltages in a series circuit?
The rule for voltage in a series circuit is that the signed sum of the voltage drops around the circuit add up to zero. This is Kirchoff's voltage law. Take a simple circuit of a 1.5V battery and light bulb in series with each other. Starting at the battery negative terminal, the voltage from negative to positive is +1.5V. Starting at the top of the light bulb (the end connected to the battery positive terminal), the voltage from top to bottom is -1.5V. The two drops (rises, in this case), +1.5V and -1.5V add up to zero. Note that the simple example above, is also a parallel circuit. The implication is that elements of a parallel circuit have the same voltage across them. Lets add a second bulb in series with the first. The voltage going up across the battery is still +1.5V, while the voltage going down across each bulb is -0.75V. Again, the sum is zero. You can take this to any level of complexity during circuit analysis. Find the series or parallel elements and calculate drops around the series part or find the equivalent voltages across the parallel parts, combine that with other techniques such as Kirchoff's current law, and Norton and Thevanin equivalents, and you can analyze any circuit. ANSWER: In a series circuit since the current remains the same for every items the voltage will vary according to ohm law
How is voltage spread out in series circuit?
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
Why is voltage split over a series circuit?
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.

If you add the IR drop or voltage drop of each individual resistance in a series circuit is it equal to the applied voltage?
Yes
If you add an extra bulb to your series circuit what will happen to the brightness of the bulbs?
The bulb is dim.Because,the voltage is drops in series connection so you add more bulbs in series the last bulb got low voltage that reason for the bulb is dim
What are the rules in series circuit?
Kirchoff's Current Law: The current at every point in a series circuit is the same. This can also be expressed as the sum of the currents entering a node is zero. Kirchoff's Voltage Law: The sum of the voltage drops across all elements in a series circuit add up to zero.
Does the voltage consumed by bells deternine entirely the voltage required from the transformer?
Yes, completely. Kirchoff's voltage law states that the sum of the signed voltage drops going around a series circuit add up to zero. The voltage produced by the transformer is completely consumed by the bell when the button is pressed completing a series circuit.
When two cells with the same voltage are connected in a series circuit what happens to the voltage?
There is addition of voltage. Dry cells have 1.5 volts irrespective of there size. if the cells are added as same polarity in series it will add if are parallel then voltage remains same
Is Voltage the same all parts of a series circuit?
Voltage is an electrical force or pressure that causes current to flow in a circuit. It is an additive in a series circuit.
What happens to voltage and current in series circuits?
Kirchoff's voltage law states that the signed sums of the voltage drops in a series circuit add up to zero.Kirchoff's current law states that the current everywhere in a series circuit is the same, more specifically, that the signed sums of the currents entering a node is zero.
What is the voltage of a series circuit with four voltage drops of 30 volts?
there is 120V across the circuit.
What is the behavior of current and voltage in a series cricuit?
Kirchhoff's Current Law: The sum of the signed currents entering a node is zero. A consequence of this is that, in a series circuit every node only has two connections, one entering and one leaving, thus, in a series circuit, the current is the same at every point. Kirchhoff's Voltage Law: The sum of the signed voltage rises going around a series circuit is zero. This means, for example, that if you have two voltage drops, such as two bulbs in series with a battery, the voltage drops across them will add up to the voltage across the battery.
