A dc source with internal resistance is connected to three identical resistors each of resistance as shown in the figure. If the thermal power generated in the circuit is highest, then 
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
In case of the highest power generated the value of internal resistance should be equal to a total external resistance, here all three external resistance are connected in parallel, ⇒R0=R3⇒R=3R0
