28. $400 Question from Daddy's Ohm
After a long day at school, you finally get to sit home and relax. You turn on your 120 Volt Nintendo that uses a current of 10 amps and your television that has a potential difference of 42, with 0.5 amps. Suddenly, you realize your living room circuit breaker will power off if you have more than 95 Ohms of resistance.
Will your Circuit breaker power off? Why or why not?
Main Board
Answer

29. $400 Answer from Daddy's Ohm
120 V/10 A = 12 Ω Nintendo
42 V/0.5 A = 84Ω TV
96 Ω Total.
Yes it will turn off, too much resistance!

Answer

41. $500 Answer from Star Watts Episode VII
26W/10V = 2.6A
14W/10V=1.4A
94W/10V=9.4A
10V/2.6A=3.85Ω
10V/1.4A=7.14 Ω
10V/9.4A=1.06Ω

A clothes dryer in a home has a power of 4,500 watts and runs on a special 220-volt household circuit
What is the current through the dryer? 
What is the resistance of the dryer? 
How many kilowatts are used by the dryer?  
How many kilowatt hours of electricity are used by the dryer if it used for 4 hours in one week?
If your town charges $0.15/kWh, what is the cost to use the clothes dryer for a month? (If there are four weeks in a month)
Answer
Main Board

53. 4 Weeks in a month – 4 x 18 kWh x $0.15 = $10.80
Final Jeopardy Answer
A=4500W/220V = A
Ω = 220V/20.45A = Ω
4500W = 4.5kW kW x 4 hours = 18 kWh
4 Weeks in a month – 4 x 18 kWh x $0.15 = $10.80
