A DC source with internal resistance \(R_0\) is connected to three identical resistors each of resistance \(R\) as shown in the figure. If the thermal power generated in the circuit is highest, then
- A \(R=2 R_0\)
- B \(R=3 R_0\)
- C \(R=\frac{R_0}{3}\)
- D \(R=R_0\)
Answer & Solution
Correct Answer
(B) \(R=3 R_0\)
Step-by-step Solution
Detailed explanation
For maximum power, \(R_0=R_{\mathrm{eq}}\) of circuit. Given, resistances are in parallel combination, the equivalent value is…
