What is the difference between junction law and Kirchhoff 's law explain with a diagram.
ANSWER THIS QUESTION I WILL GIVE YOU ALL 8 POINTS.
Answers
Kirchhoff's first rule ( Kirchhoff's Current Law or KCL or Junction Rule) :
It state that, the sum of the currents flowing towards a junction is equal to the sum of currents leaving the junction.
This is in accordance with the conservation of charge which is the basis of Kirchhoff's current rule.
I1+I2-I3-I4-I5=0
"In an electric network, the algebraic sum of currents meeting at a junction is always zero".
∑ I =o
Kirchhoff's second rule ( Kirchhoff's Voltage Law or KVL Loop rule ) :
It states that the algebraic sum of all potential drops and emfs along any closed path in a network is zero.
OR
The algebraic sum of the emfs in a loop of a circuit is equal to the algebraic sum of the product of current and resistances in it.
Mathematically, the loop rule may be expressed as :
∑ E = ∑IR
