kirchoffs law
Kirchhoff's voltage rule:-
If several souces of emf and several resistors are connected in some complicated circuit with severl branches,then the currents will flow along several alternative paths.Kirchhoff's voltage rule can be applied to any loop in the complicated circuit.
Mainly the two Kirchoff's rules are
1.Kirchoff's current rule (or) Junction theorem
2.Kirchoff's Voltage rule
1.Kirchoff's current rule (or) Junction theorem:-
sum of the currents entering the Junction at any point is equal to sum of the currents leaving same junction.
(or)
The Algebraic sum of all currents at any Junction in the circuit is Zero
Equation:-
I+I1+I2+I3+I4+I5+............=0
sum of the emf source is equal to the sum of the potential difference across the resistor
The Algebraic sum of all the potential difference across all the elements in closed loop is Zero
V+V1+V2+V3+V4+V5+........=0
