Manga Guide to Electricity Exercise

Average $0.10 per KWH

Electric Burner

120V 750 W 6.25A roughly 2 hours per 24 hour period

where h=hours

750W x 2h=1.5kWh

1.5kWh=$0.15

Air Conditioner

115V 494.5W 4.3A roughly 6 hours per 24 hour period

where h=hours

494.5W x 6h=2.967kWh

2.967kWh=$0.30

Phone Handset Base (Charger)

9V 1.89W 210mA less than 1 hour per 24 hour period

where h=hours

1.89W x 0.5h=0.000945kWh

0.000945kWh=$0.01

Fan

120 V 40W 33.3mA roughly 6 hours per 24 hour period

where h=hours

40W x 6h=0.24kWh

0.24kWh=$0.02

PC Speakers

4.5V 2.7W 600mA roughly 6 hours per 24 hour period

where h=hours

2.7W x 6h=0.0162kWh

0.0162kWh=$0.02

1 breaker can handle 20A

6.25A + 4.3A + 0.21A + 0.333A + 0.6A=11.3933A

20A / 11.3933A = 1.755417657746219

If all 5 appliances formed a Megatron Appliance of 11.3933A I could plug in 1.755417657746219 of them into a single breaker.
