2nd problem:

3x^-2 X (3x²)^-1

 A real battery with emf 12.0 V and internal resistance 2.00 Ω is connected to a resistance of 4.00 Ω.

a. What is the current through the battery?

b. What is the terminal voltage of the battery?  

A thin long conductor of length L = 60cm connected to a battery of emf 12V, and internal resistance r = 0.80 Ω carries a current I. The long conductor has resistance R = 5.0 Ω. The wires that connect theconductor to the battery have negligibleresistance.


What is the value of I?
