Lecture#9: Other Single Loop Circuits (internal resistance of the battery and resistors in series)

What's the difference between an ideal and a real battery?
How to calculate the current in a circuit when the battery is real, i.e., the internal resistance is taken into account?
How to find the equivalent resistance of more than one resistors connected in series?
What is mean't by resistors connected in series?
How to apply Loop Rules of Voltage to a circuit?
All figures and equations have been taken from Fundamental of Physics by Halliday, Resnick and Walker, 10th Edition.
