    current in series is 2.50 mA

    current in parallel is 13.51 mA

    Explanation:

    given data

    voltage = 5 V

    resistors R1 = 1.5 kilo ohms

    resistors R2 = 0.5 kilo ohms

    to given data

    current flow

    solution

    current flow in series is express as here

    current = voltage / resistor ... 1

    put here all value in equation 1

    current = 5 / (1.5 + 0.5)

    current = 5 / 2.0

    so current = 2.50 mA

    and

    current flow in parallel is express as

    current = voltage / resistor ... 2

    put here all value in equation 2

    current = 5 / (1 / (1/1.5 + 1/0.5))

    current = 5 / 0.37

    so current = 13.31 mA
