    By definition, the power is equal to the product of the current high squared by the value of the resistance.

    In other words:

    P = I ^ 2 * R

    where,

    I: Current

    R: resistance

    If we double the resistance in a circuit but keep the current in it constant, then:

    P = (I ^ 2) * (2 * R)

    P = 2 * (I ^ 2 * R)

    The power increases twice.

    answer:

    The power dissipated by that circuit will increase twice
