Question

16. Your basement suite is really drafty, so you spend your birthday money on the biggest space heater you can afford. It is rated at a hefty 1200W, and you hope it can help to warm your apartment

After you get it home you start to wonder whether the wiring in your house can handle the load of this heater. You determine that each room in your house has a fuse rated at 15 A and the voltage in the wall plugs is 120 V. You also note that the temperature inside your home is 20 degrees Celsius and outside 8 degrees Celsius.

Will your fuse break when you turn on this heater? (Be sure to justify your answer with a calculation and/or explanation) Need more help please with physics..and thank you for helping out .

Explanation / Answer

The maxium power load each room can bear without melting the fuse = VI = 120 V * 15 A = 1800 W

Power load of heater = 1200 W

Since, the load by heater has below the safety limit of fuse melting, hence it will not melt
