All the Electricity: Manga Guide, Circuit Board, and Balloon Experiment

The Manga Guide to Electricity

Calculate how much it costs to use five common appliances that you use every day in your home for 24 hours. Please let me know the appliance, its wattage, amps and volts of each appliance and how you calculated cost. You will need to go to GRU or look at one of your electric bills.

How many of those appliances can you pug into one outlet without tripping a breaker? Please do this mathematically rather than through direct experience.


After reading The Manga Guide to Electricity and looking at the question I chose the dishwasher, microwave, refrigerator, hair straightener, and ceiling fan. 

Dishwasher: 1200W, 110V, 10.9 amps, 1.2kwh
- Average cost: $0.94 per use

Microwave: 750W, 220V, 3.4 amps, 0.75kwh
- Average cost: $0.59 per use

Refrigerator: 727W, 220V, 3.29amps, 0.725kwh
- Average cost: $0.57 per hour, $13.68 for 24 hours

Hair Straightener: 1200W, 110V, 10.9amps, 1.2kwh
- Average cost: $0.94 each use

Ceiling Fan: 70W, 120V, 0.583amps, 0.70kwh
- Average cost: $0.05 per hour, $1.20 per day (24 hours)

Not many of my appliance would you be able to plug into the wall while having all of them on. Definitely not the dishwasher or the refrigerator. Although the hair straightener I feel varies with the outlet

What is the directional relationship between charge and current?
The directional relationship depends on the magnetic force while being a source of the magnetic field. Current is the rate of charge that goes past a given point. The flow of current it opposite of that of the electron charge.
