Extracted text: (a) Diode is made from n-type and p-type extrinsic semiconductors. Figure Q1(a) shows an example of electrical circuit using diodes. (i) Explain the different in forming n-type and p-type extrinsic semiconductor. (ii) Depletion region is a region between n-region and p-region in diode structure. By using your own word, explain what caused the depletion region to become narrow. (iii) Calculate the value of V, and I, for the circuit in Figure Q1(a). Ge 15V O Si Si 6.6kN Figure Q1(a) : Electric circuit using diode (b) Figure Q1(b) shows a bridge rectifier circuit using germanium diodes. (i) State the rectifier circuit type. (ii) Draw the output waveform, vo for the circuit.
