Inicialmente debemos calcular la resistencia, para ellos aplicaremos la Ley de Ohm, tenemos:
P = V²/R
R = V²/P
R = (120V)²/40W
R = 360Ω
Una bombilla de 40 W y 120 V tiene un valor de 360Ω.
Ahora, procedemos a calcular el calor, tenemos:
Q = 0.24 · I² · R · t
Q = 0.24 · ( 2A)² · (60 Ω) · (60 s)
Q = 3456 J
Ahora, transformamos de Joule a Kilocalorias, tenemos:
Q = 0.82 Kcal
Q = 820 calorías
