consume in 1 hour?
J
(b) A color television set draws about 2.6 A when
connected to 120 V. How much time is required for it
to consume the same energy as the black-and-white
model consumes in 1 hour?

Expert Solution

Step 1

Given:

The power supply to a typical black-white TV is P=92 W.
The voltage connected is V=120 V.

Part (a)

The time to consume electrical energy is t= 1 hr.

The expression for energy (U) is:

$U = P t$

Substitute all the known values in above equation.

$U = (92 W \times \frac{1 \frac{J}{s}}{1 W}) (1 hr× \frac{3600 s}{1 hr}) U = 331200 J$

Thus, the electrical energy consume in 1 hr is 331200 J.

It seems hard to justify spending $4.00 for an LED lightbulb when an ordinary incandescent bulb costs $0.50. To see if it makes sense, compare a 60 W incandescent bulb that lasts 1000 hours to a 10 W LED bulb that lasts 20,000 hours. (These are typical values.) Both bulbs produce the same amount of visible light and are interchangeable.
An alternative to CFL bulbs and incandescent bulbs are light-emitting diode (LED) bulbs. A 100-W incandescent bulb can be replaced by a 16-W LED bulb.Both produce 1600 lumens of light. Assuming the cost of electricity is $0.10 per kilowatt-hour, how much does it cost to run the bulb for one year if it runs for four hours a day?
