#### Formula Used:

T = bl / d
n = Turns/ T
cd = (2 x n x d) + bd
r = (n x d + bd) / 2
a = PI x r x r
L = (2 x PI x r x n) / 1000
rpm = .0333 *((0.812/2)*(0.812/2))/((d/2)*(d/2))
R = rpm x L
V = R x I
P = V x I
Where,
T = Turns per winding,
bl = Length of Bobbin,
d = Wire Diameter,
n = Number of windings,
cd = Outer diameter of coil,
bd = Diameter of Bobbin,
r = radius of middle of coil,
a = Cross sectional area,
L = Total Length,
rpm = Resistance/meter,
R = Resistance,
V = Voltage at Rated Current,
I = Current,
P = Power at Rated Current,
Determining the **physical properties of coil / material ** is made easier with this electrical calculator.
