Give one real-life example in Computers of Deadlock 

and how to prevent it from occurring?

Determine the value of the anode current in the Figure below when the device is ON. 

VBR(F) =100V. Assume VBE=0.7V and VCE(sat) =0.1V for the internal transistor structure. What is the resistance in the forward conduction region of the 4-layer diode.

A 4-layer is biased in the forward –blocking region with an anode-to-cathode voltage of 20V under this bias condition, the anode current is 1uA. Determine the resistance of the diode in the forward-blocking region.

A JFET produces gate current of 20nA when gate is reversed biased with 8V. Determine the resistance between gate and source.

The device parameters for n-channel JFET are maximum drain current (IDSS) = 10mA, pinch-off voltage (Vp) =-4V

Calculate the drain current for 

(a) VGS= 0V (b) VGS=-1V (c) VGS=-4V

Three balanced Y-connected loads are installed on a balanced three-phase four-wire system. Load 1 draws a total power of 6 kW at unity PF, load 2 pulls 10 kVA at PF  0.96 lagging, and load 3 demands 7 kW at 0.85 lagging. If the phase voltage at the loads is 135 V, if each line has a resistance of 0.1 , and if the neutral has a resistance of 1 , find (a) the total power drawn by the loads; (b) the combined PF of the loads; (c) the total power lost in the four lines; (d) the phase voltage at the source; (e) the power factor at which the source is operating.
