Formulae on Alternating Current





Important Formula #1

Average Power consumed in the circuit



    
   

Important Formula #2





Tips and Tricks on Capacitance



Tip #1






   

Tip #2

In series ,charge remains the same and potential across the capacitors may be different .In parallel ,potential difference across each capacitor on the capacitors may be different


Formulae on Capacitance


Important Formula #1




   

Important Formula #2




Tips And Tricks on Center of Mass, Impulse and Momentum





Tip #1

Linear momentum is conserved whenever external force is zero or in a two body system net external force is zero.





    
   

Tip #2

Elastic collision occurs only in atomic or subatomic particles. In real world, collision is inelastic .Only collision between two ping-pong balls may be considered elastic. During elastic collision kinetic energy and linear momentum are conserved.
