1 Describe how a JFET differs in construction from a bipolar transistor. 2. Describe how a MOSFET conducts a current

A ferrite ETD44 core type material is to be used in the converter design. If Bmax = 0.52T, and 350 turns of 1.5x10³cm² copper wire is to be wound around the core material to allow a flow of 5A maximum current, compute for the (a) inductor resistance, and the (b) inductance.

Please answer the questions 1 c, and d with details on why it is true or false. Please make handwriting legible. Thank you.

The positive peak value of output waveform for the given circuit diagram is...... (VPP of input is 14 V, Bias voltage is 4 V, Diode is germanium) R1 I D, VIN VouT

Determine the peak phase deviation for a PM modulator with deviation sensitivity K = 3.8 rad/V and a modulating signal vm= 12 sin(2π1000t).

Assuming the diodes to be ideal. For the circuit shown below: (a) Find the transfer characteristics (vO vs vI) of the circuit. (b) Draw the transfer characteristics (vO vs vI).

1) AC power in a load can be controlled by using a. Two SCR's in parallel opposition b. Two SCR's in series c. Three SCR's in series d. Four SCR's in series 2) The advantage of using free - wheeling diode in half controlled bridge converter is that a. There is always a path for the ac current independent of the ac line b. There is always a path for the dc current independent of the ac line c. There is always a path for the dc current dependent of the ac line d. There is always a path for the ac current dependent of the ac line 3) Silicon controlled rectifier can be turned on a. By applying a gate pulse and turned off only when current becomes zero b. And turned off by applying gate pulse c. By applying a gate pulse and turned off by removing the gate pulse d. By making current non zero and turned off by making current zero

The operating point is also called the . ..... ..... .. Select one: a. Cut off point b. Saturation point c. Quiescent point d. None of the above

Describe how a silicon wafer is manufactured starting with pure solid silicon and explain why this is important to the function of solid state devices.

Helli. I only need the last part. Plotting power vs voltage if used as a solar cell and give the definition of  fill factor. Tnx
