Q:The plates of a capacitor are connected to a battery. What happens to the charge on the plates if the connecting wires are removed from the battery?Q:Explain why a dielectric increases the maximum operating voltage of a capacitor even though the physical size of the capacitor doesn’t change.Q:(a) The equivalent capacitance for a group of capacitors connected in parallel is (i) Greater than the capacitance of any of the capacitors in theQ:If a current of 80.0 mA exists in a metal wire, how many electrons flow past a given cross section of the wire in 10.0 min? Sketch the direction ofQ:A certain conductor has 7.50 x 1028 free electrons per cubic meter, a cross-sectional area of 4.00 x 10–6 m2, and carries a current of 2.50 A. FindQ:A 1.00-V potential difference is maintained across a 10.0-Ω resistor for a period of 20.0 s. What total charge passes through the wire in this timeQ:In a particular television picture tube, the measured beam current is 60.0 µA. How many electrons strike the screen every second?Q:In the Bohr model of the hydrogen atom, an electron in the lowest energy state moves at a speed of 2.19 × 106 m/s in a circular path having a radiusQ:If 3.25 × 10–3 kg of gold is deposited on the negative electrode of an electrolytic cell in a period of 2.78 h, what is the current in the cellQ:A 200-km-long high-voltage transm
