In a series circuit:
Add up the individual resistances of each component.
The sum is the effective (total) resistance.
In a parallel circuit:
-- Take the reciprocal of each individual element.
-- Add up all the reciprocals.
-- Take the reciprocal of the sum.
The answer is the effective (total) resistance.
If you have a complex circuit with both series and parallel sections in it:
-- First, find the effective resistance of each parallel section, and replace each one
with a single equivalent resistance.
-- Now you're left with only a series circuit to solve, by summing the individual resistances.

∙ 12y ago"Total" voltage does not differ because of the difference between parallel or series circuits. Unless the circuits are batteries.
If you daisy-chained six 1.5 volt batteries in series the total voltage would be 9 volts.
If you hooked six 1.5 volt batteries up parallel you would get a total voltage of 1.5 volts with a higher ma/hr rating

∙ 12y agoThe easy way is to measure the voltage between the terminals of the power supply
that's energizing the series circuit. The other way is to measure the voltage across
each element, component, and piece of wire in the series circuit and add them all up.
The two methods produce identical numbers. If they don't, then you made a mistake
in at least one of them, and maybe both.

How can you find the steady state current in RLC series circuit?
-- If the excitation source is AC, then the steady state of the circuit depends on the voltage, frequency, and waveform (harmonic content) of the source. -- If the excitation source is DC, then the steady state current in a series circuit is zero. DC doesn't pass through a capacitor.
What do parallel circuit NOT have in common with series circuit?
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
How do you find resistance in a circuit?
That entirely depends on whether the resistances are in series or in parallel with each other. Ohm's law states that I=V/R. i.e. current = voltage/resistance. If you know the current and voltage you can find the resistance. You can use algebra to rearrange the formula for R and get that R= V/I. Resistance = voltage/current.
What is the use of superposition theorem?
superposition can find the voltage and current effect of each source to a particular branch of the circuit and we can calculate the total effect of the sources to know the effect of the total sources to that branch
How do you find power in a circuit?
P=IV Power=current x voltage
How do you find unknown value of a resistor when total resistor values and voltage are known in a series circuit?
A: If you know the total resistance and total voltage then you know total current flow for the circuit, this current will be same for every resistor in series however the voltage drop will change for each resistor . So measuring the voltage drop across the resistor in question and divide by the total current will give you the resistor value.
What are the relation between individual voltage and the total voltage when resistors are connected in series?
when A resistance is connected across the supply voltage, total input vooltage will be drop in the resistance when the resistances are connected across the supply voltage, total input vooltage will be devidedacross the resistances. IF R value will be high ,drop also high. IF R value wll be low ,voltage drop will be less.
How do you find power in a series circuit?
Power dissipated by the entire series circuit = (voltage between its ends)2 / (sum of resistances of each component in the circuit). Power dissipated by one individual component in the series circuit = (current through the series circuit)2 x (resistance of the individual component).
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 do you find resistance when you have current and resistance total?
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
How do you find power in parallel circuit?
Voltage will be same in all branches. Voltage= Current * Total Resistance
To find the current in a complex circuit it is necessary to know?
the source voltage and the total impedanceAnswerA 'complex circuit' describes a category of circuit that is neither series, parallel, nor series-parallel. A relatively-simple example of a complex circuit is a Wheatstone Bridge. You cannot analyse or resolve a complex circuit using the techniques used to analyse and resolve series, parallel, or series-parallel circuit. Instead you must use one or other of the various electrical theorems. For example, to determine the currents flowing in a Wheatstone Bridge circuit, you could use Kirchhoff's Laws or Thevenin's Theorem.
How do you find current in a compound circuit with parallel and series circuits?
Current in a parallel circuit divides between the branches, depending on the relative impedance of each branch. Kirchoff's current law, which can be used to analyze that current, states simply that the sum of the currents entering and leaving a node, properly signed, always add up to zero.Current in a series circuit is the same at every point in the circuit. This is a consequence of Kirchoff's current law, because a node in a series circuit consists of only two conductors, and the sum of the currents at that node must be zero. By implication, then, all nodes in a series circuit must have the same current.Not asked, but discussed due to completeness, is Kirchoff's voltage law, which states that the signed sum of the voltage drops around a series circuit always add up to zero. A consequence of this is that the voltage across elements of a parallel circuit must be the same.
How can you find the steady state current in RLC series circuit?
-- If the excitation source is AC, then the steady state of the circuit depends on the voltage, frequency, and waveform (harmonic content) of the source. -- If the excitation source is DC, then the steady state current in a series circuit is zero. DC doesn't pass through a capacitor.

How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
Why Kirchhoffs current law and Kirchhoffs voltage law cannot apply on distributed circuits?
Actually, they do apply.Kirchoff's Current Law states that the signed sum of the currents entering a node is zero. This applies whether the node has only two connections, such as in a series cicuit, or more than two connections, such as in a parallel circuit. Some people confuse this with the rule that current at every point in a series circuit is the same. That is just a special case of KCL, but the real rule has to do with the node, and not the circuit.Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. This applies for simple series circuits as well as for complex series/parallel circuits. Pick any loop in a circuit and walk around it - you will find that the signed sum of the voltage drops is zero, no matter what.
