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.

What is the difference between series and parralal circuit?
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
What is the relationship between the current leaving the source and the current through each load in a series circuit?
A: In a series circuit the current remains the same for each components only the voltage across each component will change and only if the components are of different value.
What is the function of series pass transistor?
A series pass transistor allows the voltage to pass to the rest of the circuit. The current goes around the part of the circuit like an IC for example, that would be destroyed if too much current were to pass through it. Series pass transistors allows small voltages and small current parts, to control higher voltages and currents than they presently cannot do by themselves.
A circuit that has only one path for the current is called?
Series, because everything in the circuit is in series.
Can the total of the voltage drops across the loads of a series circuit ever exceed the total of the source voltages applied to that circuit?
No. But bear in mind that, in the case of a.c. circuits, 'total', means the phasor (vectorial) sum of the voltage drops, NOT the algebraic sum.
Which circuit would have the highest voltage series or parellel?
There's no correspoindence, correlation, or connection between those characteristics. A series circuit or a parallel circuit may have high or low voltages.
How are parallel circuit and series circuit the same?
They are not. They are connected differently, and the voltages and currents behave in different ways.
Can the total of the voltage drop across the loads of a series circuit ever exceed the total of the source voltages applied to that circuit?
no
What is true about the sum of the voltages across the components in a circuit compared to the voltage of the cell?
voltage is devided only in series circuit and is the same at the parallel circuit
What is the relationship between the voltage output at the interface and the voltage across the series and parallel circuit?
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
What are the relations between individual voltages and the total voltages when resistors are connected in series and in parallel?
-- The current in each individual resistor is (voltage across the whole circuit) divided by (the resistance of the individual resistor). -- The current in any individual resistor is less than the total current in the circuit. -- The total current in the circuit is the sum of the currents through each individual resistor.
If two light-bulbs are connected in a series circuit and one of the light-bulb's current flowing is 0.5 A what is the current flowing in the other light-bulb?
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
What kind of circuit is one in which all parts are connected in a single loop?
That is a series circuit, all parts have the same current flowing through, and the voltages add up.
What is the difference between series and parralal circuit?
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
What is the relationship between the potential difference across a battery and the potential difference across each load in a parallel circuit?
Without specifics (are all the batteries end to end or are some loads between batteries, are all the loads the same resistive, capacitive or inductive value...), the generic answer is: the sum of supplied voltages must equal the sum of voltage drops across the loads.
What is the relationship between the current leaving the source and the current through each load in a series circuit?
A: In a series circuit the current remains the same for each components only the voltage across each component will change and only if the components are of different value.
What is the function of series pass transistor?
A series pass transistor allows the voltage to pass to the rest of the circuit.
