Question
In a circuit shown in figure resistances R1 and R2 are known, as well as emf′s E1 and E2. 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 ?
Options
A.R1 + R2
B.R1 − R2
C.
D.
Solution
For maximum power across the resistance, R is equal to equivalent resistance of remaining resistance
R =
R =
