In a circuit shown in figure resistances R 1 and R 2 are known, as well as emf ’ s E 1 and E 2 . The internal resistances of the sources are negligible. At what value of the resistance R will the thermal power generated in it be the highest?
A
R 1 + R 2
B
R 1 – R 2
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
For maximum power across the resistance, R is equal to equivalent resistance of remaining resistance
R =
