A 1500-W heater is connected to a 120-V line for 2.0 hours. How much heat energy is produced?

A 1500-W heater is connected to a 120-V line for 2.0 hours. How much heat energy is produced?

Solution

here,

power of heater , P = 1500 W

time , t = 2 hours

t = 7200 s

the heat energy produced , E = p * t

E = 1500 * 7200

E = 10800000 J

the heat energy produced is (4) 11 MJ
