  • question_answer
    The circuit shown here has two batteries of 8.0 V and 16.0 V and three resistors \[3\Omega \], \[9\Omega \,\] and \[9\Omega \,\] a capacitor of \[5.0\text{ }\mu F.\] How much is the current I in the circuit in steady state?          

    A) 1.6 A

    B) 0.67 A

    C) 2.5 A

    D) 0.25 A

    Correct Answer: B

    Solution :

    [b] In steady state capacitor is fully charged hence no current will flow through line 2. By simplifying the circuit Hence resultant potential difference across resistances will be 8.0 V. This current \[\text{or, }I=\frac{2}{3}=0.67A\]
