    Answer: 3 Amperes

    Explanation:

    Voltage of battery = 24 volts

    R1 = 3Ω

    R2 = 5Ω

    Total resistance = ?

    Current, I = ?

    Since the resistors are connected in series, the total resistance (Rtotal) of the circuit is the sum of each resistance.

    i. e Rtotal = R1 + R2

    Rtotal = 3Ω + 5Ω = 8Ω

    Now recall that voltage = current x resistance

    i. e V = I x Rtotal

    24volts = I x 8Ω

    I = 24 volts / 8Ω

    I = 3 amperes

    Thus, there is 3 Amperes of current in the circuit
