Explain p - Type semiconductor.
p - Type semiconductor:-
(i) If small amount of trivalent impurity is added with to a pure semiconductor giving a large no. of holes in this, the extrinsic semiconductor therefore formed is termed as p- type semiconductor. This addition of trivalent impurities as gallium and indium give a large no. of holes in the semiconductor crystal. Theses impurities, that produce p- type semiconductors, are termed as acceptor impurities since each atom of them creates one hole that can accept one electron.
(ii) The majority and minority charge carriers are holes and electrons correspondingly.
(iii) The impurity level is here above the valence band.
Magnetic circuits To see how this is used in practice, consider a coil of N turns wound onto a closed ring shaped former with a very high (note: r (steel) = 200
explain with figure
Q. Show television waveform? The television waveform representing one scan is illustrated in Figure. A blanking pulse with a duration of 0.18 of the horizontal - sweep period T
8 bit data to memory This form of the instruction is used to copy 8 bit data directly to the memory location pointed by register pair HL. The instruction format is
Q. What happens when a negative bias is applied to the gate of a FET? The result of applying a negative bias to the gate is to reach the saturation level at a lower level of V
Q. Explain by using a circuit diagram, a ‘Darlington Pair'. Mention its advantages? THE DARLINGTON PAIR : This is a very special way of direct coupling of two transistors. The
Consider the circuit shown in Figure (a) in which the switch S has been in position 1 for a long time. Let the switch be changed instantaneously to position 2 at t = 0. Obtain v(t)
Q. Show polarity markings for a single-phase transformer for (a) subtractive polarity, and (b) additive polarity.
The per-phase synchronous reactance of a three-phase, wye-connected, 2.5-MVA, 6.6-kV, 60-Hz turboalternator is 10 . Neglect the armature resistance and saturation. Calculate the v
Define a voltmeter A voltmeter is an instrument used to measure p.d. and must be linked in parallel with the part of the circuit whose p.d. is required.
