Kirchhoffs Laws are statements about circuits. There are two laws ; 1) The total current entering any point in a closed circuit equals the total current leaving that point. 2) The sum of the voltage changes around any closed path is zero. These "Laws" are a consequence of the more fundamental laws of conservation of charge and conservation of energy.

∙ 14y agoKirchoff's Current Law states that the sum of the currents going in and out of a node is zero. When you look at this, you must use one sign, such as positive, for current entering, and the other sign, such as negative, for current leaving. One consequence of the law is that the current at every point in a series circuit is the same.

∙ 14y agoKirchoff's current law states that the signed sum of the currents in a series circuit add up to zero. Stated another way, the current at every point in a series circuit is the same.
This law can be used, along with Kichoff's voltage law, Ohm's law, Norton and Thevanin equivalents, and other transformations to analyze various circuits.
A specific example of Kirchoff's current law is the analysis of a transistor. If you know the current through the collector or emitter resistor, you can assume (within reasonable limits) that the current through the other resistor is the same. (The "limits" have to do with the contribution from the base current, but that is generally negligible)

∙ 6y agoKirchhoff's Laws for current and voltage are two principles that apply to DC circuits and networks. The total current flowing into any DC circuit node, also called a branch point, is always the same as the total current flowing out of the node.

What state of matter obey's Boyles law?
Liquid The Boyle law is for gases !!
Which law state that energy cannot be created or destroyed?
law of conservation of energy.
What states have energy laws that state that energy can not be created or destroyed?
Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
Does Boyle's law state that as the temperature of a gas increases the voulme increases?
Boyle has no law.
How do you derive joule's law?
State and derive joul's law of heating effect of an electric current.
State Kirchoffs voltage and current law?
Kirchoffs Current Law : [KCL]This law is also called Kirchhoff's point rule, Kirchhoff's junction rule (or nodal rule), and Kirchhoff's first rule. The principle of conservation of electric charge implies that: : At any point in an electrical circuit that does not represent a capacitor plate, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point. Kirchoffs Voltage Law : [KVL]This law is also called Kirchhoff's second law, Kirchhoff's loop (or mesh) rule, and Kirchhoff's second rule. : The directed sum of the electrical potential differences around any closed circuit must be zero.Kirchoffs Laws are widely used in the Electrical and Electronic engineering fields.Hope this helps =)
What is kirchoff voltage law and kirchoff current law?
kirchoffs voltage law : the algebric sum of all voltage drop is equal to algebric sum of voltage risekirchoffs current law : algebric sum of all current entering at a node is equal to algebric sum of current leavingCommentIt's Kirchhoff, not 'Kirchoff'!
What determines the structures of political parties at the state level?
State Law
What is the application of kirchoffs voltage law?
Kirchoff's Voltage Law: The sum of the voltage drops across all elements in a series circuit add up to zero. If you know the voltage drops across all but one element, and you know the voltage rise across the source, then you can easily calculate the remaining drop.
If the current is 10 amperes in the main wire and 4 amperes in one of the branches how much current is in the other branch?
Six, Voltage is the same in a parallel circuit but current divides to total the sum of each branch. See Kirchoffs current law.
What is the different between a state law and a federal law?
A state law is created by the state and only pertains to that single state. A federal law is created by the national government and is enforced throughout the whole nation. Federal law overrides state law.
Does state law have precedence over law law?
No the constitution states that government law is superior to state law.
Is eminent domain a State law Federal law or both?
State law
Do state law prohibits public criticism of state official?
The law will be upheld because it's a state law and is consistent with the state constituion.
When a state calls a federal law invalid?
State law can be more detailed than federal law, but cannot conflict with federal law. Therefore, a state law cannot determine that a federal law is invalid. The state would have to, instead challenge the federal law as an unconstitutional intrusion on state rights.
Where there is a state there is always law and where there is law there is always a state?
yes
What happens when a state law conflicts with federal law?
If the state law is stricter/harsher/more limiting, state law takes precedence. If the the state law is more lax/unrestricted, federal law takes precedence.
