Specify the LM-series linear regulator required to regulate a fixed voltage of -19 V. Please write the numbers only in the answer field: i.e. for LM1234, you would write 1234 in the answer field.

Refer to your lecture notes. In a CRT, electrons leave the filament as the current through the filament heats it up. An anode then attracts the free electrons. As the electrons emerge from the small aperture of the anode, they move in the z direction toward the X- and Y-plates. If an oscillating voltage is applied to the Y-plates, this will happen. a. The electron beam will be deflected up and down. O b. The electron beam will stop. O c. The electron beam will continue as normal. O d. The electron beam will be deflected to the right and to the left.

Please answer in typing format solution Sir please help Thanks in advance

3.16 A three-phase, full-wave half-controlled rectifier bridge circuit is operating at a delay angle a = 67° when supplying full power. The per-phase inductance of the coupled transformer is 2 mH. The input voltage has an rms magnitude of 230 V per phase at 50 Hz. The load current in the d.c. side is 15 A at 200 V. It is required to: (a) Obtain the drop in the d.c. voltage due to current overlap. (b) Calculate the rms secondary voltage of the transformer. (c) Calculate the overlap angle. (d) Obtain the recovery angle while the converter in operating in the inversion mode with 15 A, 200 V d.c. input. (e) Obtain the firing angle for the conditions in (d). [Ans: (a) 4.5 V, (b) 450 V, (c) 1.06°, (d) 67.14°, (e) 111.8°]

Q1 a. Consider you have to choose b/w the Full-Wave Bridge Rectifier (FWBR) & Center-Tapped Full Wave Rectifier (CT-FWR) in one of your semester Lab projects. (1) Discuss the advantages of FWBR over CT-FWR which will justify, why to select the FWBR.
