KIRCHOFF'S LAW

FIRST LAW

• KCL

Kirchoff's Current Law

-the sum of current entering the node

is equal to the current leaving the node

 

NODE????

- when two or more branches 

 is connected to each other

 BRANCH????

-has a single element 

with each terminals 

 

SECOND LAW

• KVL

Kirchoff's Voltage Law

-states that the sum of voltages in a loop

is always equal zero

LOOP????

 - is any continuous path available 

for current flow from a given point in a circuit and 

back to that same point in the circuit from the 

opposite direction that it left from without 

crossing or retracing 

it`s own path.

 

LEARNINGS:

 

For getting the current I3 in the circuit

using KCL process, you must add the current 

that enters the node and subtract the current that 

leaving the node, then equal to zero.
