1.Un calentador eléctrico tiene una resistencia de 26Ω. Si el calentador se conectaa una fuente de voltaje de 91V, calcula la corriente que fluye a través del calentador y la potencia que disipa. 2.Una corriente de 7A fluye a través de una plancha eléctrica con una resistencia de 15Ω. Calcula el voltaje o tensión eléctrica en los extremos de la resistencia y la potencia que disipa.
3.Calcula el voltaje y la potencia disipada por un calentador eléctrico de 18Ω cuando una corriente de 5A fluye a través del mismo. Si el calentador permanece conectado a la fuente durante 10 horas, calcula la energía consumida y el costo, asumiendo que el costo de 1 kWh es de $0.83.
