 Aman said: (Mar 13, 2019) According to this, if you want to simplify the voltage then it will be, V=R * A(V=>31 * 3.5 = 108.5). Voltage means to push, so push must have to multiply by A(amount of electron) and R(anti-push). And if you want to simplify the R(anti-push). Then, R(anti-push) = V(push)/A(amount of electron), R = V/A.

 Er.J.Arun Ganesh said: (Oct 22, 2019) As per ohms law, Voltage V = 110. Current I = 3.5. Resistance R = X. Formula, R = V/I. R = 110/3.5 = 31.42 ohms. Resistance of heating element is 31.42 ohms.
