    Answer

    the current is 0.17amps

    Explanation:

    This problem bothers power of an electrical circuit.

    Electric power is defined as the electric heat transferred per second. This can be expressed as

    P=IV

    P= V²/R

    P= I²R

    Given data

    Power p= 7.04w

    Resistance R=236 ohms

    Using the third equation and Substituting our data we have

    7.04= I²* 236

    I²= 7.04/236

    I= √0.029

    I= 0.17amps
