The frequency of a clocking signal is 10MHZ and it is used to sample serial data stream. If the data must be stable for 15ns before the leading clock edge and for 10ns after the leading clock edge, how much time is available to change the data between clock pulses?
In a typical commercial electrical distribution system, which is more common: an inductive power factor, or a capacitive power factor. What is the most common technique used to correct this kind of low power factor.
Find the input torque to the generator.If armature current and field current are kept constant, find the new value of the terminal voltage if the power factor is changed to 0.7 lagging.
