  • question_answer
      The battery of a trunk has an emf of 24 V. If the internal resistance of the battery is \[0.8\text{ }\Omega \]. What is the maximum current that can be drawn from the battery?

    A) 30 A      

    B) 32 A

    C) 33 A                

    D) 34 A

    Correct Answer: A

    Solution :

    (a) 30 A Here, \[\varepsilon =24\,V\]and \[r=0.8\text{ }\Omega \] For the maximum current from the battery             \[\varepsilon =lr(\because \,R=0)\] \[\therefore l=\frac{\varepsilon }{r}=\frac{24}{0.8}=30\,A\]
