007 (part 1 of 4) 10.0 points An object with a resistance of 17 has 130 V applied to it. How much electric current is going through this object? Answer in units of amps. 008 (part 2 of 4) 10.0 points How much power is being produced by the object? Answer in units of W. 009 (part 3 of 4) 10.0 points How much electric energy will be needed to operate this object for 15 h? Answer in units of kWh. 010 (part 4 of 4) 10.0 points What is the cost of operating this object for 15 h at a rate of 6.8 cents/kWh? Answer in units of S

Explanation / Answer

1 I = V/R = 130/7 = 18.6 A  
2. Power = VI = 2414 W
3. Energy = power x time
= 1.3x105 J
4. Cost = energy x rate = 2.46 $
