The energy consumption ratio is the product of the time interval ratio and the power (or current) ratio.
The current ratio is
Pbd/Pvc = 12/5.5
The energy ratio is
Ebd / Evc =
Pbd/Pvc * Tbd/Tvc = (12/5.5)*(19/30)
= 1.382
A blow-dryer and a vacuum cleaner each operate with a voltage of 120 V. The current rating of the blow-dryer is 12 A, and that of the vacuum cleaner is 5.5 A.
Determine the power consumed by the blow-dryer.
Determine the power consumed by the vacuum cleaner.
Determine the ratio of the energy used by the blow-dryer in 19 minutes to the energy used by the vacuum cleaner in one-half hour.
Ebd / Evc =
the first two parts i got but the last im not sure what to do.
