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 flowing through it. What is the potential difference across the terminals of the battery?
