A student is provided with a 12.0-V battery of negligible internal resistance and four resistors with the following resistances: 100 Ohms, 30 Ohms, 20 Ohms, and 10 Ohms. The student also has plenty of wire of negligible resistance available to make connections as desired. 1. Using all of these components, draw a circuit diagram in which each resistor has nonzero current flowing through it, but in which the current from the battery is as small as possible. 2. Using all...
