php bipolar junction transistor. [2 marks] (ii) Sketch a diagram of pnp bipolar junction transistor and mark for each region in the diagram the type of majority carriers and the names given to each of these regions, Briefly explain why one region is very thin with respect to the others. [6 marks] (iii) Explain how to polarise the pnp transistor in forward active mode, rank the values of potential to apply to each region of the transistor. [3 marks] (b) In the circuit below, Vcc is 5 volts, the resistors are 5 k2, and when a transistor is in saturation the voltage drop between its emitter and collector is 0.2 volts. (i) If A and B are both grounded, determine the electrical potential in Q. [2 marks] (ii) If A and B are set at 5.0 volts, determine the potential in Q. [2 marks] (iii) If A is set at 5.0 volts and B is grounded, determine the potential in Q. [2 marks] (iv) Write a truth table describing the value of Q with respect to the two inputs A and B. What logic gate does the circuit correspond to? [3 marks] -Vcc A B-C
