A 5V charger is connected to a smart phone. The charger can supply 1.5A. The phone requires 54kJoules to become fully charged. How long does it take for the phone to get fully charged?
Suppose the battery on your phone delivers a current of 0.770 mA (that's milliAmperes) over a time of 3.00 hours. What is the total charge that flows out of the battery during this time? How many electrons flow out of the battery during this time?
An electric device delivers a current of 3 A to a device. How many electrons flow through this device in 8 s? (e = 1.60 × 10-19 C)
In comparing wires of identical shape and carrying the same current but made of different metals, is the drift velocity in each wire inversely proportional to the number density of charge carriers? No. The drift velocity is the same for all conductors. Yes. To have the same current from k times as many carriers, it takes k times the drift speed. No. The drift velocity is directly proportional to the number density of carriers. Yes. To have the same current...
Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s this lasts for 100 μs or less. 1.How much charge flows between the ground and the cloud in this time? (Q= ? C) 2.How many electrons flow during this time? (n_e = ? )
The electromagnetic wave that delivers a cellular phone call to a car has a magnetic field with an rms value of 1.90 10-10 T. The wave passes perpendicularly through an open window, the area of which is 0.20 m2. How much energy does this wave carry through the window during a 60-s phone call?
The electromagnetic wave that delivers a cellular phone call to a car has a magnetic field with an rms value of 1.8 × 10-10 T. The wave passes perpendicularly through an open window, the area of which is 0.23 m2. How much energy does this wave carry through the window during a 32-s phone call?
The electromagnetic wave that delivers a cellular phone call to a car has a magnetic field with an rms value of 1.30 × 10-10 T. The wave passes perpendicularly through an open window, the area of which is 0.39 m². How much energy does this wave carry through the window during a 41-s phone call? Joules
