As per the system given, machine B will receive the active and reactive power from machine A when ______________

As per the system given, machine B will receive the active and reactive power from machine A when they are electrically connected and machine A operates in a mode that is capable of generating or transferring both active and reactive power to machine B. This requires machine A to be operating as a generator or an energy source, and there must be a suitable medium or connection for transferring this power, such as power lines or cables. Additionally, both machines must be synchronized in terms of voltage, frequency, and phase for the power transfer to be efficient and safe.
