A 60 w (120 v) night light is turned on for an average 12 h a day year round. part a what is the annual cost of electricity at a
1 answer:
The annual cost of electricity is $28.908 .
work done is equal to energy consumed
therefore total energy is calculated as power times the duration of operation .
where W= work done
P=power
t= time of operation
therefore,
total work done (W)=0.06×12×365 kw
=262.8 kw
so total annual electricity bill = 262.8×0.11
=$28.908
