1. A silicon diode has a forward current of 500 mA at 1 V. Use the third approximation to calculate its bulk resistance.
2. Given a silicon diode with a reverse current of 5 a at 25°C and 100 μA at 100°C, calculate the surface leakage current.
For a 12-bit linear PCM code with a resolution of 0.02 V, determine the voltage range that would be converted to the following PCM codes. (a) 1 0 0 0 0 0 0 0 0 0 0 1 (b) 0 0 0 0 0 0 0 0 0 0 0 0 (c) 1 1 0 ..
A 1 A diode can deliver 1 A up to 75ºC with a derating factor of 8.5 mA/ ºC (this means that the current must be reduced by 8.5 mA for each degree above 75ºC). How much current can be drawn at 110 ºC
Consider an RLC circuit with R = 5 Ohms, L= ½ H, C= 2/9 F and input voltage e(t) = exp(-t/2)a. Starting from KVL show that the DE for the voltage across R is given by: v'' + 10 v' + 9 v = -5 exp(-0.5 t) b. Find vc in terms of the arbitrary constants ..
A 120 V, 60Hz source is connected to a distribution line whose resistance and inductive reactance is .001 Ohm and j0.002 Ohm respectively. A single phase, 100 HP, 120V, 0.85pf motor and a 100 kW, 120 V Heater are connected in parallel.

Explain the operation of sequential logic devices and evaluate the output waveform in relation to the clock for QA, QB and QC in the subsequent circuit and show the binary sequence represented by these waveforms
Mass is added to the piston at a rate such that the gas is compressed according to the relationship PV1.2 = constant to a final volume of 1.8 ft3. Find the final pressure (psia), the work done in the process (lbf-ft), and the final temperature of ..
An electron in an infinitely deep potential well of thickness 4 Å is placed in a linear superposition of the first and third states. What is the frequency of oscillation of the electron probability density
Perform a logical shift right by 4 positions on each of the following unsigned numbers to form a 12-bit result: 100101010000 and 000101001000. In each case, does the result exactly represent division by 16?
Due to saturation effects, the flux at an armaturecurrent of 25A is 45% of that at an armature current of 75A. Findthe motor speed when the armature voltage is 230V and the armature current is 25A.
