The rate of heat dissipation in an AC circuit is given by formula P = V^2/R, where V is the effective voltage across the circuit. We know that V = Ieff * R, where Ieff is the effective current of the AC circuit. So we can substitute V in the formula for P and get: P = (Ieff * R)^2 / R Simplifying this, we get: P = Ieff^2 * R Substituting the given values, we get: P = (I_rms)^2 / R which is equivalent to option B.
