depend on the R value(s) because V Source = Sum of individual voltage across each R in the series so if R in the series are equal value, then their V are the same and their V total will be equal of the V Source
In a series circuit, the total voltage drop across resistors which are across a voltage source is equal to the voltage of the source.
Consider the wires between the source and the resistors. They have effectively zero ohms impedance. Ohm's law states that voltage is current times resistance. With a resistance of zero ohms, the voltage drop across the conductor is also zero.
This can also be summarized with Kirchoff's voltage law: The sum of the voltage drops around a series circuit always adds up to zero. If you start at an arbitrary point, such as the bottom of the voltage source, and then go through the voltage source, you have a rise equal to the voltage source. Continuing around the circuit, the voltage drop across each resistor must be subtracted (rise equals plus, drop equals minus, or whatever convention you want to use) and by the time you get back to the starting point, you must have an accumulated voltage of zero.
A: ACTUALLY it is not .If it is is because the source is constant and since the parallel load are across it seems like the voltage is constant. in a series circuit every different Resistance will have a different voltage across it
If you mean the voltage is the same among the different branches, this follows from Kirchof's Laws.

By installing the varialble resistor in the circuit,the constant dc voltage would change .
If you are asking how a voltmeter should be connected in a circuit, then the answer is that it should be connected in parallel with the device across which you want to determine the voltage. This applies whether the circuit is d.c. or a.c.
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
The current in each individual component of the parallel circuit is equal to (voltage across the combined group of parallel components) / (individual component's resistance). The total current is the sum of the individual currents. ============================== Another approach is to first calculate the combined effective resistance of the group of parallel components. -- take the reciprocal of each individual resistance -- add all the reciprocals -- the combined effective resistance is the reciprocal of the sum. Then, the total current through the parallel circuit is (voltage across the parallel circuit) / (combined effective resistance of the components).
A Voltage Quadrupler would be a DC circuit. A transformer would be used to increase the voltage in an AC circuit. To quadruple the voltage in a DC circuit would consist of (min) 4 resistors. 1 resistor would be directly in parallel with the power source, that is, one side of the R would be connected to one side of the source, and the other side of the R would be connected to the other side of the source. The remaining resistors are configured in a sort of series/parallel with the 1st resistor to increase (ladder fashion) the output voltage. See the related links for a more detailed explntn.

Connecting 12 volt DC batteries in parallel will increase amperage available, but voltage will remain 12 volts.

in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
IF two dc sources are connected in parallel, the one with the highest potential dominates the circuit.
chopper use a ststeing perpose..... dc means direct current that is low voltage
multiply the total voltage in the circuit by the total amperage
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
