A voltmeter is attached to the terminals of an "unloaded" or standalone battery. The meter reads 12.2 V. What is the EMF of this battery? What is the terminal voltage of this battery? How much current is flowing through the battery? In the previous problem, a 120 2 resistor is placed across the terminals of the battery. A voltmeter reading across the battery terminals now shows a voltage of 11.4 V. A) How much current is flowing through the resistor? B) How much current is flowing through the battery? C) What is the internal resistance of the battery? From the previous problems (EMF = 12.2 V, R₁ = 120 2), calculate A) the current flowing through the circuit if a second resistor with R₂ = 240 2 is placed in series with the first one. B) What is the new terminal voltage of the battery, if different from the original terminal voltage?
