Part A, B, E, please  An external resistor with resistance R  is connected to a battery that has emf E and internal resistance r. Let P be the electrical power output of the source. By conservation of energy, P is equal to the power consumed by R. Part A What is the value of P in the limit that R is very small? For the emf E of the battery use the notation E.  Part B What is the value of P in the limit that R is very large? For the emf E of the battery use the notation E. Express your answer in terms of some or all of the variables R, r, and E. Part E A battery has E= 64.0 V and r= 4.00Ω. What is the power output of this battery when it is connected to a resistor R, for R= 2.00 Ω?
