A battery with nonnegligible internal resistance, a variable resistor, a voltmeter, and an ammeter are connected as shown above on the left. The graph above on the right shows the voltmeter reading as a function of the ammeter reading as the resistance, R, of the variable resistor is changed. What is the internal resistance of the battery? (A) 0.5 (B) 20 (C) 4 (D) 8 () 12 (A) (V) R V(V) 12 8+ 4- + 4 8 12 | (A) A battery with nonnegligible internal resistance, a variable resistor, a voltmeter, and an ammeter are connected as shown above on the left.
