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...

When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance, you measure a current of 17.2 mA flowing through it. What is the resistance of this resistor? If you now place the resistor across the terminals of a 12.4 V car battery having no internal resistance, how much current will flow? You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of \(0.451\) A...
