A three-phase, wye-connected, cylindrical-rotor synchronous generator rated at 10 kVA and 230 V has a synchronous reactance of 1.5per phase and an armature resistance of 0.5 per phase.
(a) Determine the voltage regulation at full load with: (i) 0.8 lagging power factor, and (ii) 0.8 leading power factor.
(b) Calculate the power factor forwhich the voltage regulation becomes zero on full load.
Q. Consider an ampli?er as a voltage source with an internal resistance of 72 . Find the turns ratio of the ideal transformer such that maximum power is delivered when the ampli?e
Q. Why the gain of the amplifier decreases if the CE is avoided? When the ce is connected in the circuit, ac signals get bypassed through it to the ground. In the absence of Ce

Question: (a) The conversion of a time varying analog audio signal into digital form is carried out using an electronic circuit known as a (signal) encoder. Draw a labeled bl
Q. Find load resistance and voltage? Let the amplifier block be connected to a current source at the input terminals, as shown in Figure(a), and to a load resistance R L at it
Define HRQ? The hold demand output requests the access of the system bus. In non- cascaded 8257 systems, this is linked with HOLD pin of CPU. In cascade mode, this pin of a sla
What are the Advantages of using robots - They are able to work non-stop; they don't need a break - They are capable of working in conditions hazardous to humans - Ess
Q. Illustrate Signal attenuation? Signal attenuation in many channels can be offset by using amplifiers to boost the signal level during transmission. However, the amplifier al
Q. Show Balanced three-phase loads? Three-phase loads can be connected in either wye (also known as star or Y) or delta (otherwise known as mesh or ). If the load impedances i
