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.

You connect a battery, resistor, and capacitor as in Fig. 26.20a, where R = 12.0 Ω and C = 5.00 x 10-6 F. The switch S is closed at t = 0. When the current in the circuit has a magnitude of 3.00 A, the charge on the capacitor is 40.0 x 10-6 C. (a) What is the emf of the battery? (b) At what time t after the switch is closed is the charge on the capacitor equal to 40.0 x 10-6 C? (c) When the current has magnitude 3.00 A, at what rate is energy being (i) stored in the capacitor, (ii) supplied by the battery

In the circuit, in Fig. E26.47 the capacitors are initially uncharged, the battery has no internal resistance, and the ammeter is idealized. Find the ammeter reading (a) just after the switch S is closed and (b) after S has been closed for a very long time.


An electron at pointAinFig. E27.15has a speedv0of1.41×106m/sFind (a) the magnitude and direction of the magnetic field that will cause the electron to follow the semicircular path fromAtoB, and (b) the time required for the electron to move fromAtoB.

A 1.50-mcylindrical rod of diameter 0.500cmis connected to

a power supply that maintains a constant potential difference of 15.0Vacross

its ends, while an ammeter measures the current through it. You observe that

at room temperature (20.0C)the ammeter reads 18.5Awhile at 92.0Cit

reads 17.2A. You can ignore any thermal expansion of the rod. Find (a) the

resistivity at and (b) the temperature coefficient of resistivity at for the material of the rod.

An emf source with E = 120 V, a resistor with R = 80.0 Ω, and a capacitor with C = 4.00 µF are connected in series. As the capacitor charges, when the current in the resistor is 0.900 A, what is the magnitude of the charge on each plate of the capacitor?
