Distinguish the drift speeds of conduction electrons from their random-motion speeds, including relative magnitudes. If the current carried by a conductor is tripled, what happens to (a) the charge carrier density, (b) the current density, (c) the electron drift velocity, and (d) the average time interval between collisions? If the current in a resistor is I, the power delivered to the resistor is P. If the current in the resistor is increased to 31, what is the power then delivered to the resistor? (Assume the resistance of the resistor does not change.) Show that when a capacitor is discharged through a resistor, the total energy stored in the capacitor is dissipated as heat in the resistor. A 5.00 nF capacitor with an initial charge of 5.50 C is discharged through a 2.30 k resistor. (a) Calculate the current in the resistor 9.00 us after the resistor is connected across the terminals of the capacitor. (b) What charge remains on the capacitor after 8.00 s? (c) What is the maximum current in the resistor? Distinguish the drift speeds of conduction electrons from their random-motion speeds, including relative magnitudes.
