What effect, if any, does increasing the resistance in an RC circuit have on the charging of the capacitor?
a) The resistance has no effect on the charging of the capacitor, which is determined by the emf of the battery and the capacitance of the capacitor. b) Increasing the resistance causes the charging time to increase since the rate at which charges are moving to the capacitor increases. c) The charging time will increase as the resistance is increased because the rate at which charges are moving to the capacitor decreases. d) Increasing the resistance increases the charging time since the emf of the battery will be reduced. e) Increasing the resistance decreases the charging time since the emf of the battery will be reduced.
