    How much current will flow through a resistor of resistance \[\text{12 }\Omega \] if a battery of 18 V is connected across it?

    A) 3.0 A                                    

    B) 4.5 A                    

    C) 1.5 A                                    

    D) 6.0 A                    

    Correct Answer: C

    Solution :

    From Ohm's law, \[R=12\,\Omega \] \[V=18\,V,I=?\,I=\frac{V}{R}=\frac{18}{12}=1.5\,A\]
