The capacity of a storage battery, such as those used in automobile electrical systems, is rated in ampere-hours .A battery can supply a current offor or for and so on. (a) What total energy can be supplied by a battery if its internal resistance is negligible? (b) What volume (in litres) of gasoline has a total heat of combustion equal to the energy obtained in part (a)? (See Section 17.6; the density of gasoline is .) (c) If a generator with an average electrical power output ofrole="math" localid="1655719210000" is connected to the battery, how much time will be required for it to charge the battery fully?
Question: A conducting sphere is placed between two charged parallel plates such as those shown in Figure. Does the electric field inside the sphere depend on precisely where between the plates the sphere is placed? What about the electric potential inside the sphere? Do the answers to these questions depend on whether or not there is a net charge on the sphere? Explain your reasoning.
A 1.50- F capacitor is charging through a 12.0-鈩� resistor using a 10.0-V battery. What will be the current when the capacitor has acquiredof its maximum charge? Will it beof the maximum current?
Suppose a resistor R lies alongeach edge of a cube (12 resistors in all)with connections at the corners. Find theequivalent resistance between two diagonally opposite corners of the cube (pointsa and b in Fig. P26.84).
The potential difference across the terminals of a battery is 8.40 V when there is a current of 1.50 A in the battery from the negative to the positive terminal. When the current is 3.50 A in the reverse direction, the potential difference becomes10.20 V . (a) What is the internal resistance of the battery? (b) What is the emf of the battery?
