Kanthal Build Cheatsheet

Just a little something I thought would be helpful to share. It's a little cheatsheet I made in notepad to help me have easy access to values and formulas =)

OHM's Law:


V = Voltage
R = Resistance
I = Current


The formula:
V = R*I --Solving Voltage
R = V/I --Solving Resistance
I = V/R --Solving Current


==================================================
Wire resistance values:


AWG 20: Low Resistance (0.07 ohms/inch)
AWG 22: Low Resistance (0.11 ohms/inch)
AWG 24: Low Resistance (0.175 ohms/inch)
AWG 26: Low Resistance (0.28 ohms/inch)
AWG 28: Low - Standard Resistance (0.44 ohms/inch)
AWG 30: Low - Standard Resistance (0.70 ohms/ inch)
AWG 32: Low - Standard Resistance (1.1 ohms/ inch)
AWG 33: Low - Standard - High Resistance (1.39 ohms/inch)
AWG 34: Standard - High Resistance (1.76 ohms/inch)


Dual coil = Resistance / 2


Quad = resistance / 4


Single = No math


==================================================


Formulas:


KEY:
----------------------
Ohm per inch = R |
total Ohms = P |
length in inches = L |
----------------------


Single Coil
---------------
P = R*L --Solving for Total Ohms
R = P/L --Solving for Ohms per inch
L = R/P --Solving for length in inches




Dual Coil
---------------
(Ohm per inch * Length in inches) / 2 = Total Ohms
(Ohm Total * Length in Inches)*2 = Resistance
(Ohm Total / Ohm per inch)*2 = Length


P = (R*L)/2 --Solving for Total Ohms
R = (P*L)*2 --Solving for Ohms per inch
L = (P/R)*2 --Solving for length in inches




Quad Coil
---------------
(Ohm per inch * Length in inches) / 4 = Total Ohms
(Ohm Total * Length in Inches)*4 = Resistance
(Ohm Total / Ohm per inch)*4 = Length


P = (R*L)/4 --Solving for Total Ohms
R = (P*L)*4 --Solving for Ohms per inch
L = (P/R)*4 --Solving for length in inches

This may help some too. Glad to see someone learning ohms law for a change. Just make sure you learn battery safety. With Mech's make sure and us the locking mechanism. http://www.steam-engine.org/coil.asp?s=dp&r=0.8&awg=28&id=2.5
