    Answer:

    P = 4.5 watts

    Explanation:

    Given that,

    EMF of the circuit, E = 3 volt

    The resistance  of the resistors, R = 2 ohms

    We need to find the power of this circuit. The relation between power, emf and resistance is given by the formula as follows :

    P=\dfrac{V^2}{R}

    Substitute all the values,

    P=\dfrac{3^2}{2}\\\\P=4.5\ W

    So, the power of this circuit is equal to 4.5 watts.
