The voltage across secondary winding of a single phase transformer is 230 v, 50 hz and the transformer deliver power to resistive load of r= 2 through a single phase half wave controlled rectifier. If the firing angle of thyristor is 45o, calculate (a) average dc output voltage, (b) rms output voltage, (c) rms output current, (d) form factor, (e) voltage ripple factor, (f) rectification efficiency, (g) transformer utilization factor and (h) piv of thyristor.

This law is applicable only if the following Conditions are met..
1 - Two Bodies having Mass
2 - There must be Some Distance between them
According to Universal Gravitional Law :
(i)The Gravitional force Between two bodies having mass m1 and m2 directly depends on the product of their masses and
(ii) Inversely Proportional to the Square of distance between them...
F = Gravitional force
m1 and m2 are the masses of bodies
r = Distance between the bodies having masses m1 and m2...
Now from statement (i) and (ii) we must have
F = G m1 x m2 / r^2 ----(iii) where G is the constant of proportionality..called Universal gravitional Constant.....
According to relation (iii)..if mass of the body increases then F will increase too...and decreases if the distance between them increases...
