Get started for freeA typical small flashlight contains two batteries, each having an emf of
A 12.4-µF capacitor is connected through a 0.895-MΩ resistor to a constant potential difference of 60.0 V. (a) Compute the charge on the capacitor at the following times after the connections are made: 0, 5.0 s, 10.0 s, 20.0 s, and 100.0 s. (b) Compute the charging currents at the same instants. (c) Graph the results of parts (a) and (b) for t between 0 and 20 s
You want to produce three 1.00-mm-diameter cylindrical wires,
each with a resistance of 1.00 Ω at room temperature. One wire is gold, one
is copper, and one is aluminum. Refer to Table 25.1 for the resistivity
values. (a) What will be the length of each wire? (b) Gold has a density of
What will be the mass of the gold wire? If you consider the current price of gold, is
this wire very expensive?
(a) What is the potential difference
If a “75-W” bulb (see Problem 25.35) is connected across a 220-V potential difference (as is used in Europe), how much power does it dissipate? Ignore the temperature dependence of the bulb’s resistance.
