WebThe sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units as hs = cp ρ q dt (1) where hs = sensible heat (kW) cp = specific heat of air (1.006 kJ/kg oC) ρ = density … Web21 de may. de 2024 · I also know that if I hook up a wire heating element to a circuit the energy from the current doesn't all get deposited in the heating element; the element radiates heat away (like in a toaster, that is what it is supposed to do). A small wire radiates a lot of heat, as it has a high surface-to-volume ratio.
Web17 de jul. de 2007 · The amount of heat produced by an electric current flowing in a conductor is given by: Q = I 2 *R*t. where Q is heat; I is current; R is resistance of the conductor; t is time. Or one can say the the resulting work done by the electric current is heat. This gives rise to a second formula: W = V*I*t.
