Every day a certain household uses a 3,3 kW electric stove for 72 minutes, six
6 hours each and miscellaneous appliances amounting to 1,6 kW h. The 3 kW hot w
ninutes during the day. If electricity costs 35 c a kWh
A 1⁄2 hp motor draws a current of 4.0 A from a 120-V line. (a) Calculate the electric power used by the motor. (b) Calculate the motor’s efficiency – that is, the work it does per unit time divided by the electrical power it uses.
Calculate the current through a 2.5 Ω flashlight filament when connected across two 1.5-V batteries (potential difference of 3.0 V). (b) Calculate the resistance of the heating elements in a toaster if 10-A current flows when connected across a 120-V potential difference.
