1. Draw the schematic symbols of NPN transistor and PNP transistor and name the three leads B, E, and C of a NPN transistor. 2. Describe how to set up the biasing-voltages VB, V and Ve in order for an NPN transistor to function in the circuit as shown in Figure 1. If the NPN transistor is a Silicon transistor what is the voltage difference VBE in the circuit? VRL Ic In VO Output loop VRB + B V V BB RB Input loop E Vcc Figure 1 An NPN transistor circuit 3. Describe the relationships of three transistor currents 1g, IE and Ic in a functional NPN transistor circuit as shown in the Figure 1. 4. In the transistor circuit as shown in Figure 1, if R = 5602, VBE = 0.7V, VBB=6V, R = 1.2K, Vcc = 15V, and the NPN transistor DC gain Bpc = 100, find the current Ig.Ic V, and VCE
