Question

Can someone please explain Kirchhoff's voltage and current laws to me? (particularly the voltage one) Thanks

Answer 1

Kirchhoff's Current Law can be stated as the sum of all current flowing into a junction is zero.

And as for Kirchhoff's Voltage Law the sum of all voltage drops and rises in a closed circuit is zero.

Remember the equation: Heat Loss = Heat Gain.
Here, Current Entering The Junction = Current Going Out of the Junction.[for current law]

Sum of Drops of Voltage = Sum of Rises of Voltage

Answer 2

Kirchhoff's Current Law
Kirchhoff's Current Law, also known as Kirchhoff's Junction Law and Kirchhoff's First Law, defines the way that electrical current is distributed when it crosses through a junction - a point where three or more conductors meet. Specifically, the law states that:
The algebraic sum of current into any junction is zero.
Since current is the flow of electrons through a conductor, it cannot build up at a junction, meaning that current is conserved: what comes in must come out. When performing calculations, current flowing into and out of the junction typically have opposite signs. This allows Kirchhoff's Current Law to be restated as:
The sum of current into a junction equals the sum of current out of the junction.

Answer 3

Kirchhoff's Current Law in action
In the picture to the right, a junction of four conductors (i.e. wires) is shown. The currents i2 and i3 are flowing into the junction, while i1 and i4 flow out of it. In this example, Kirchhoff's Junction Rule yields the following equation:
i2 + i3 = i1 + i4

Answer 5

kirchhoff's second law support's the law of consevation of energy

Answer 6

differemce b/w I ND II law ;
first law -
1) support the law of consevation of "CHARGE"
2) sigma i=0
3)can be used in open /close circuits.

second law;
1)support the law of consevation of 'ENERGY"
2)\[\sum_{}^{}E=\sum_{ }^{}IR\]
3)CAN BE USED IN CLOSED CIRCUIT

Answer 7

note that E is emf .
