3. Four resistors are connected to a battery with an emf of 9.00 V (neglect internal resistance) as shown in the diagram. A switch SW1 can be in the "up," "down," or "open" position. (When it is open, it is not connected to either of the two terminals.) The current through the battery when the switch is in the three different positions is as follows: up, 1.90 mA; open, 1.10 mA; down, 1.40 mA. Find the resistances R₁, R₂, and R3. + R1 w IMM SW1 R2 ww R3 R2 3. Four resistors are connected to a battery with an emf of 9.00 V (neglect internal resistance) as shown in the diagram.
