Q16:Four resistors are connected to a battery as shown in Figure P28.16.
(a) Determine the potential difference across each resistor in terms of e.
(b) Determine the current in each resistor in terms of I.
(c) What If? If R3 is increased, explain what happens to the current in each of the resistors.
(d) In the limit that R3 S `, what are the new values of the current in each resistor in terms of I, the original current in the battery?
