    Understanding Joule's Law and Power: How Does It Relate to Heat and Resistance?

    total resistance in series is Rt=R1+R2+...+Rn and in parallel 1/Rt=1/R1+1/R2+...+1/Rn. Joule's law sais Q=I^2*R*t where Q the heat generated by a constant current.If (I) and (t) are constant Q is proportionate to R so in series Q will increase more than when the resistors are in parallel.Correct?

    Understanding Joule's Law and Power: How Does It Relate to Heat and Resistance?

    Hello, i want to ask 2 questions: 1-what is the difference between joule's heat and power? 2-We have 2 different resistors.How joule's heat ,which is created in them, will change if they connect to a steady voltage source:(a)in series,(b)in parallel Thank you
