when you connect an unknown resistor across the terminals of a 1.50 V AAA battery having a negligible internal resistance, you measure a current of 18.0 mA flowing through it .A)what is the resistance of the resistor. B) if you now place the resistor across the terminals of a 12.6 v car battery having no internal resistance,how much current will flow? .C)you now put the resistor across the terminal of an unknown battery of negligible internal resistance and measure the current of 0.453 A flowing through it, what is the potential difference across the terminals of the battery ?
