Question 2
- State Kirchhoff’s current law.
 - In figure 1, calculate
 
                     
- V;
 - I2;
 - I3;
 - I.
 
Observation
- Kirchhoff’s current law:
 
              The algebraic sum  of currents flowing into a node in a circuit is zero.
    OR
    The algebraic sum  of currents flowing out of a node is zero
    OR
    The sum of currents flowing into a node is  equal to sum of current flowing out of the   
    node.
