Concept explainers

Ohm's law

Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.

Path of Least Resistance

In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.

Compact fluorescent tubes cost $15 each and have an estimated life span of 8,000 hours. These tubes consume 20 W of power, but produce illumination equivalent to that of 75 W incandescent bulbs. These cost $3.75 each and have an estimated life span of 1,200 hours. If a home has, on average, six 75W incandescent bulbs on constantly and energy costs $0.2875 per kilowatt-hour, how much money will a consumer save each year by installing fluorescent tubes instead?
