    Answer:

    R = 0.1 ohms

    Explanation:

    It is given that,

    Voltage of the battery, V = 12.5 V

    Current flowing in the car’s starter, I = 125 A

    We need to find the effective resistance of a car’s starter. It can be calculated using Ohm’s law. Let R is the resistance.

    V=IR\\\\R=\dfrac{V}{I}\\\\R=\dfrac{12.5}{125}\\\\R=0.1\ \Omega

    So, the resistance of the car’s starter is 0.1 ohms.
