Question

Which one of the following statements is true: The reactive power is the power dissipated in the form of heat by the network. The reactive power is the power delivered to a load without considering the effects of the power-factor angle of the load. The apparent power is the power delivered to a load without considering the effects of the power-factor angle of the load. The real power is the power associated with reactive elements that provides a measure of the energy associated with setting up the magnetic and electric fields.

    Answer:

    The apparent power is the power delivered to a load without considering the effects of the power-factor angle of the load

    Explanation:

    If I and V are the current and voltage across the load, the apparent power, = IV

    Since,

    apparent power = active power + reactive power

    active power = IVcosФ

    reactive power = IVsinФ

    So, IV = IVcosФ + IVsinФ

    where I = current, V = voltage and Ф = power factor angle.

    We see that the apparent power is the product of the current, I and the Voltage, V without considering the power factor angle of the load.

    So, the apparent power is the power delivered to a load without considering the effects of the power-factor angle of the load.
