$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

$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! Main Board

Final Jeopardy 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

4 Weeks in a month – 4 x 18 kWh x $0.15 = $10.80 Final Jeopardy Answer A=4500W/220V = 20.45A Ω = 220V/20.45A = 10.76 Ω 4500W = 4.5kW 4.5kW x 4 hours = 18 kWh 4 Weeks in a month – 4 x 18 kWh x $0.15 = $10.80 Main Board
