Question:

Three equal resistors (R) are connected to a battery as shown in Fig. 19-42. Qualitatively, what happens to?

(a) The voltage drop across each of this resistor,
(b) The current flow through each,
(c) The terminal voltage of the battery, when the switch S is opened, after having been closed for a long time?
(d) If the emf of the battery is 15.0V, what is its terminal voltage when the
switch is closed if the internal resistance 1s 0.50Ω? (e) What is the terminal voltage when the switch is open?
