    Answer:

    The total resistance is 106 Ω and the current in the circuit is 0.11 A.

    Explanation:

    Given that,

    Voltage of the battery, V = 12 V

    Resistors 34 Ω, 42Ω, and 30Ω are connected in series.

    The total resistance is given by :}

    R = 34 + 42 +30

    = 106Ω

    Let I is the total current in the circuit. Using ohm’s law to find it such that,

    I=\dfrac{V}{R}\\\\I=\dfrac{12}{106}\\\\I=0.11\ A

    Hence, the total resistance is 106 Ω and the current in the circuit is 0.11 A.
