Inscribed And Circumscribed Circle in a Triangle

Circle Inscribed In a Triangle

    It is a circle inside a triangle that touches all sides of it. Formula to find the area of the circle is

Radius = (2√(k(k-a)(k-b)(k-c)))/a+b+c

Where k=(a+b+c)/2

            a,b,c= three sides of the triangle

Area of the inscribed is = pi*radius^2

Circumcircle Of A Triangle

It is a circle that touches all the vertices of a triangle. The formula to find the area of the circle

 Radius = abc/4At 

    Where abc are the three sides of the triangle and

                At is the area of the triangle

DC Machines

Things to remember in a DC Machine

1. EMF equation of a DC motor or generator = (fi*Z*N*P)/60A

Where, fi = flux/pole
             Z= number of armature conductors
             N= Speed in RPM
             P= Number of poles
             A= number of parallel paths i.e A=2 in case of wave winding and A=P(number of poles) in                        case of lap winding
   
     2. Speed = 120F/P

Where f = frequency and P  = number of poles
