1.	Calculate the energy consumed in electrical units when a 75 W fan is used for 8 hours daily for one month (30 days)
Answer» <P> Solution :POWER, `p=100W` Time of usage, `t=8hourxx30days=240hours` Electrial energy consned is the product of power and time of usage. `"Electrical energy "=power xx "time of usage"=p xx t` `=75 "watt"xx240 "hou"r=18000" watt HOUR"= 18" kilowatt hour"=18kwh` `1 "electrical unit"=1 kWh` `"Electrial energy"=18 unit`
