Get started for freeLight Bulbs in Series and in Parallel. Two light bulbs have constant resistances of and . If the two light bulbs are connected in series across a line, find (a) the current through each bulb; (b) the power dissipated in each bulb; (c) the total power dissipated in both bulbs. The two light bulbs are now connected in parallel across theline. Find (d) the current through each bulb; (e) the power dissipated in each bulb; (f) the total power dissipated in both bulbs. (g) In each situation, which of the two bulbs glows the brightest? (h) In which situation is there a greater total light output from both bulbs combined?
Small aircraft often have 24 V electrical systems rather than the 12 V systems in automobiles, even though the electrical power requirements are roughly the same in both applications. The explanation given by aircraft designers is that a 24 V system weighs less than a 12 V system because thinner wires can be used. Explain why this is so.
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?
An electron experiences a magnetic force of magnitudewhen moving at an angle of 60.0° with respect toa magnetic field of magnitude. Find the speed ofthe electron.
Copper has free electrons per cubic meter. A 71.0-cm
length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 A of
current. (a) How much time does it take for an electron to travel the length
of the wire? (b) Repeat part (a) for 6-gauge copper wire (diameter 4.12 mm)
of the same length that carries the same current. (c) Generally speaking,
how does changing the diameter of a wire that carries a given amount of
current affect the drift velocity of the electrons in the wire?
