wht is the difference between KIRCHOFFS'S VOLTAGE LAW and kirchoff's current law??

difference between kcl and kvl laws

KVL means the sum of voltage across any closed loop is zero
KCL means the sum of current into one node is zero

KVL AND KCL???

KVL:
The sum of all the voltages in a closed loop is zero

KCL:
The sum of the currents leaving a node=the sum of the currents entering the node

i.e:

N1 N2 N3
o---/\/\/\/\/\/\--o---/\/\/\/\/\/\--o
I1 ---> I2 --->

here I1=I2

Sorry, the draw moves when i post it, but this is the idea

Re: KVL AND KCL???

KVL states that the sum of the elements voltage in a closed loop is zero but
KCL says that for a closed surface the algebraic sum of the currents are zero.
