1) At every point in the circuit, the current is the same.
2) The sum of the voltage drops across each component is zero.
In a series circuit, the current remains constant throughout the circuit. The voltage across each component in a series circuit adds up to the total voltage of the circuit.
Kirchoff's voltage law and Kirchoff's current law
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.
Current flows from higher voltage to lower voltage. The total current entering a junction must equal the total current leaving the junction. Resistance in a circuit reduces the flow of current.
current is constant in the series circuit. The resistances of the components add up and the potential differences is divided propotionally over the components depending on their resistances.

Boss its a circuit not a device, you can also create one of yours..... just use simple logic of voltage divider and current divider rules...-satendra.svnit@gmail.com
in parallel the voltage stays the same in parallell the current is shared in series the voltage is shared in series the current stays the same the main similarity between parallel and series circuits is when voltage increases, current increases.
In parallel circuits, the voltage across each branch is the same as the total voltage of the circuit. This is because each branch is connected directly across the voltage source. This rule is known as Kirchhoff's voltage law.
Well, this is a nice question. I will just try to answer it. Note that the combined resistance in parallel will always be less than any of the individual resistances. In the parallel system, there is a separate independent path from the source to each resistance and back to the source, therefore each has the same voltage drop. This means that the voltage must be the same at each point in the parallel circuits. There are three rules governing simple parallel circuits of resistive elements: 1. Voltage across each resistor is the same as the voltage across the parallel combination. 2. The current flowing through the parallel combination is the sum of the current in the separate branches. 3. Summing resistance of a parallel circuit can be stated as follows: The reciprocal of the total resistance is equal to the sum of the reciprocals of each of the individual resistances. So that you can have more information about series and parallel circuits, just try to visit the website....: http://elpaso.apogee.net/foe/fcsppr.asp
Turn Back NOW! This will make no sense unless you are an expert electrician! Current refers to the movement of electrical charge from one point to another. Electrons are typically the only carriers of charge in an electric circuit. Voltage is a bit more difficult to understand in concrete terms. It is related to potential energy. Electrons are attracted to positive charges and will accelerate toward them if free to move. The potential energy of an electron reflects how much kinetic energy it would have if it were accelerated all the way to the positive charge, or the amount of energy it would have taken to move the electron from the positive charge to its current position. Because electric energy is a "conservative field", these quantities are equal. The electrons don't have to move the whole distance to the positive charge, and in electric circuits we are most concerned with "potential difference" between two points partway along the path. Because electrons have a negative charge, the positive direction of current flow is actually the opposite of the direction of motion of the electrons. Also, negative voltage is where electrons have higher potential energy. Because both of these are reversed, it is rarely necessary to be aware of these inconsistencies in practice. The basic rules for analyzing a circuit follow from these facts. Since current is a measure of flow, and electrons are neither created nor destroyed, the current flowing into a point in a circuit must equal the current flowing out. Because voltage is a conservative field, voltage difference around any complete path through the circuit is 0. As much energy as an electron gains going out, it will lose returning to its original position. Voltage is defined for any particular point in a circuit, regardless of the path taken to that point. (However, voltage can change over time.) Different electrical components have characteristic relationships between the current through them and the voltage difference between their terminals, and their designed parameters. A battery has one of the simplest relationships. The voltage difference is constant regardless (theoretically) of the current. A resistor is described by the formula V1 - V0 = iR, where the voltage difference (V1 - V0) is proportional to the current (i) and the designed resistance (R) of the resistor. Connective wires have practically no resistance compared to other components in the circuit. So you can assume the voltage difference across the wire is V1 - V0 = i * 0 = 0. Therefore any terminals connected by unbroken paths of wires can be assumed to have the same voltage. Define a voltage variable for each such wired node, and a current variable for each component between these nodes. For each voltage node, write an equation adding all currents into the node, and subtracting all nodes out, and placing 0 on the right hand side. Add the characteristic equations for the components. Then solve the system of equations. It might help intuitive understanding of the equations to correctly guess the directions of the currents, but it is not necessary. The only requirement is that a current added to the equation for one terminal should be subtracted from the equation for the opposite terminal. If you guess the wrong direction for the current, the result will come out negative.
Don't let anyone touch the live electrical parts. This voltage is significantly more dangerous than 120V. If you touch it it's likely to grab you and not let go. All components must be rated for the voltage in question. Switches must be rated for 277V, as well as lights, all boxes, junctions, and all electrical wiring must have insulation rated for 277V or above. The circuit breakers must be rated for this voltage, and they must be rated for the available fault current which could pass through the wiring of the circuit, based upon this new voltage. Because this circuit is more than 150V to ground, there are more strict rules on who may perform the work. Review the rules for your locality before cracking any covers. It's likely you should be a licensed electrician before tinkering with this stuff.
