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.

Which statements about series circuits are correct?
series circuits have 1 pathway they have constant current(Amperes) not constant voltage. Resistance=R+R+R+...
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
When adding resistance in a series circuit what happens to supply voltage?
In a series circuit... Kirchoff's current law: The sum of the signed currents entering a node is zero. Since a series circuit consists of only nodes each connected to only two elements, this means that the current in every point in a series circuit is the same. Kirchoff's voltage law: The sum of the signed voltage drops in a series circuit is zero. This means, that if you segregate the sources from the loads, the total voltage across all the nodes is equal to the total voltage across all the sources. That may seem trite, but take the case where you have one battery in series with two resistors also in series. If you know the voltage across one resistor, then you know the voltage across the other resistor - it is the battery voltage minus the first resistor's voltage. Ohm's law: Voltage is current times resistance. This actually applies everywhere; series circuits, parallel circuits, DC circuits, AC circuits, etc.
Does Kirchhoff current law and Kirchhoff voltage law depend on the relationship between current and voltage in a resistor?
Kirchhoff's Voltage and Current Laws apply to circuits: series, parallel, series-parallel, and complex.If your circuit comprises just a single resistor, then they still apply. For example, the voltage drop across a single resistor will be equal and opposite the applied voltage (Kirchhoff's Voltage Law), and the current entering the resistor will be equal to the current leaving it (Kirchhoff's Current Law).
When is it usually desirable to connect cells in series?
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.

How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
Voltmeter in series circuits?
The only reason anyone will put a voltmeter in series is to measure current flow as a function of voltage drop.
Why is amps constant in a series connection?
Since the Emf(voltage) being supplied to circuit is constant then so is the current in series circuit.In parallel circuits the current is then divided depending on the resistors.but for both circuits the sum of the current in= current outAnswerIt's not necessarily 'constant', but it will be the samecurrent.

How do you measure current and voltage in circuit by kirchoff's method?
Kirchhoff (not 'Kirchoff') doesn't suggest any way of measuring current or voltage in a circuit. Kirchhoff's Voltage Law defines the relationships between potential differences around any closed loop within a circuit. Kirchhoff's Current Law defines the relationships between currents at any junction within a circuit. Kirchhoff's Laws may also be used to solve complex circuits ('complex' circuits are those circuits which are not series, parallel, or series-parallel). Current and voltage may be measured with an ammeter and a voltmeter, respectively.
Does Kirchhoff current law and Kirchhoff voltage law depend on the relationship between current and voltage in a resistor?
Kirchhoff's Voltage and Current Laws apply to circuits: series, parallel, series-parallel, and complex.If your circuit comprises just a single resistor, then they still apply. For example, the voltage drop across a single resistor will be equal and opposite the applied voltage (Kirchhoff's Voltage Law), and the current entering the resistor will be equal to the current leaving it (Kirchhoff's Current Law).
What are some types of electric circuits?
Some different types of circuits are:openclosedparallelseriesThere are two types of basic circuits, series and parallel.In series, current stays constant and voltage is divided amongst the resistors.In parallel the voltage stays constant, Every branch of the circuit gets the same voltage from the power supplier, but there is different current in every branch but current doesn't get lost. Current entering a junction(branches) must equal to current out of the junction. Iin =Iout.The third type could be the Series-Parallel Combination, which has some components wired in series and other components in parallel. Solving these circuits requires more complex analysis techniques. See related link.Another AnswerElectrical circuits are generally classified as being: (1) series, (2) parallel, (3) series-parallel, and (4) complex. The term, 'complex' is a category into which any circuit that doesn't fall into the first three categories, is placed.
What are the three basic different types of electrical circuits?
In electronics DC stands for direct current. There are three types of circuits in this current. They are the closed, open, and series circuits.
When is it usually desirable to connect cells in series?
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.
What are the 2 kind of circuit?
The two basic circuit types are series circuits and parallel circuits. In a series circuit, all the current flows through each component, and each one drops some of the applied voltage. In a parallel circuit, the applied voltage is dropped across each parallel component and current "splits" so some flows through each component.
