Chapter 4: Q38E (page 843)

A battery-powered global positioning system (GPS) receiver operating 9.0 V on draws a current of 0.13 A. How much electrical energy does it consume during 30 minutes?

Short Answer

Expert verified

The electric energy consumed by GPS in 30 min is 2100 J.

Step by step solution

01

Concept/Significance of electric current.

The passage of an electric charge is referred to as an electric current. This charge is frequently carried by moving electrons in a wire, but it can also be carried by ions or both electrons and ions, as in an ionized gas.

02

Determination of the electrical energy does GPS consume during minutes

The electric energy consumed by GPS is given by,

E=Pt=l.Vt

Here, I is the current drawn by GPS, V is the potential of the battery and t is the time taken.

Substitute all the values in the above,

E=(9.0V×0.13AS)(30m)60sm=2100J

Thus, the electric energy consumed by GPS in 30 min is 2100 J.

High-voltage power supplies are sometimes designed intentionally to have rather large internal resistance as a safety precaution. Why is such a power supply with a large internal resistance safer than a supply with the same voltage but lower internal resistance?

(a) At room temperature, what is the strength of the electric field in a

12-gauge copper wire (diameter 2.05mm) that is needed to cause a 4.50-A

current to flow? (b) What field would be needed if the wire were made of silver

instead?

Questions: When a thunderstorm is approaching, sailors at sea sometimes observe a phenomenon called “St. Elmo’s fire,” a bluish flickering light at the tips of masts. What causes this? Why does it occur at the tips of masts? Why is the effect most pronounced when the masts are wet? (Hint: Seawater is a good conductor of electricity.)

An alpha particle (a He nucleus containing two protons and two neutrons and having a mass of 6.64×10-7kg) travelling horizontally at 35.6km/senter a uniform, vertical,1.80-T magnetic field.(a) What is the diameter of the path followed by this alpha particle? (b) what effect does the magnetic field have on the speed of the particle? (c) What are the magnitude and direction of the acceleration of the alpha particle while it is in the magnetic field? (d) explain why the speed of the particle does not change even though an unbalanced external force acts on it.
