    Answer:

    R = 0.75 ohms

    Explanation:

    Given that,

    The voltage of each battery, V = 1.5 V

    Current through the light bulb, I = 2 A

    We need to find the resistance of the light bulb. We know that,

    Ohm’s law, V = IR

    Where

    R is the resistance of the light bulb

    Put all the values,

    R=\dfrac{V}{I}\\\\R=\dfrac{1.5}{2}\\\\R=0.75\ \Omega

    So, the resistance of the light bulb is equal to 0.75 ohms.
