Question

Consider the circuit given here with the following parameters E.M.F. of the cell = 12 V. Internal resistance of the cell $= 2 \Omega$Resistance $R = 4 \Omega$

Which one of the following statements in true

• A. Rate of energy loss in the source is = 8 W
• B. Rate of energy conversion in the source is 16 W
• C. Power output in is = 8 W
• D. Potential drop across R is = 16 V

Answer 1

Answer: (A)

Rate of energy loss in the source is = 8 W

Answer 2

Energy loss inside the source

$= i ^ { 2 } r$
