A battery has a terminal voltage of 12.0 V when no current flows. Its internal resistance is 2.0 Ω. If a 1.7 Ω resistor is connected across the battery terminals, what is the terminal voltage and what is the current through the 1.7 Ω resistor? Can someone point me in the right direction? I know I have to use V = E - Ir because there is a internal resistance. But I am not sure how to start... Thanks in advance.
