    Ω and 100 Ω, respectively. Calculate the speed of the generator if it is driven by a prime mover that supplies a torque of 20 Nm.

    To solve this problem, we can use the equation for the electrical power output of the generator:

    P = VI

    Where P is the power, V is the voltage, and I is the current. We can rearrange this equation to solve for the speed of the generator:

    P = Tω

    Where P is the power, T is the torque, and ω is the angular velocity (speed) of the generator.

    First, let's calculate the power output of the generator:

    P = VI
    P = (220 V)(45 A)
    P = 9900 W

    Next, let's calculate the speed of the generator:

    P = Tω
    9900 W = (20 Nm)ω

    Solving for ω:

    ω = 9900 W / 20 Nm
    ω = 495 rad/s

    Therefore, the speed of the generator is 495 rad/s.
