    1.3 Amps

    Explanation:

    We are given;

    A circuit with resistors, R1 and R2

    R1 = 7 Ω

    R2 = 11 Ω

    Voltage = 24 V

    We are required to calculate the current in the circuit.

    Step 1: We need to find the effective resistance.

    When resistors are arranged in series, the effective resistance is calculated by;

    Rt = R₁ + R₂ + R₃ + ... Rₙ

    Therefore;

    Total resistance = 7 + 11

    = 18 Ω

    Step 2: Calculate the current in the circuit

    From the ohm's law;

    V = IR

    Rearranging the formula;

    I = V/R

    Thus;

    I = 24 V : 18 Ω

    = 1.333 Amps

    = 1.3 Amps

    Thus, the current in the circuit is 1.3 Amps
