kirchoff's law soliving qs..
,
academic
points for solving numericals based upon krichoff's law :-
1)Give the naming to the corners and junctions of the circuit ( here ABCDEF )
2)Distribute current in a circuit using K.F.Law starting preferrably frm battery outside the circuit ( here E1 is most outside.)
3)Choose a close loop , if on moving the finger along the loop , the finger goes along the direction of current , current is taken as +ive , however if the finger move opposite to the direction of the current , the current is taken as -ive
4)On moving the finger along the loop , if the finger goes frm +ive to -ive pole , EMF is -ive , However if the finger moves frm -ive pole to +ive pole , EMF is taken as +ive
here...
frm closed loop BCFB
I1R2 + I2R3 - ( I - I1) R5 = E2 - E3
frm closed loop CDFC
(I1 - I2) R4 - ( I - I1 + I2 ) R6 - I2R3 = -E4 + E3
for closed loop ABFDEA
(I - I1) R5 + ( I - I1 + I2) R6 + IR1 = + E
hence by these 3 equations , we can find I , I1 & I2
