Table of different connection methods of heating elements
Power formula  OHM’S law  
P = Power in watts  U = Voltage  
U = Voltage  P = UI  R = Resistance in ohms  U = RI  
I= Current in amperes  I= Current in amperes  
I= P/U  U= P/I  I= U/R  R= U/I  P= U2 /R  R= U2 /P 
Heating elements connections
(Heating elements resistance “r” of unit power “p” with nominal voltage “U”)
Parallel wiring  Serial wiring 


Delta and star element connections
Delta connection  Star connection
