The emf of a storage battery of a car is 6.0 V. If internal resistance of the battery is \(0.2 \Omega\) then maximum power drawn from the battery is ___________ W.
- A 2.4
- B 180
- C 15
- D Zero
Answer & Solution
Correct Answer
(B) 180
Step-by-step Solution
Detailed explanation
\( P_{max} = \frac{\mathcal{E}^2}{r} \) \( P_{max} = \frac{6.0^2}{0.2} = \frac{36}{0.2} = 180 \) W
