The three-terminal device circled in (Figure 1) is an NPN transistor It works using three simple rules: 1. The net current into the device is the same as the net current out of the device, so Ic+IR - IH- II. The potential at point e is always 0.60 V less than the potential at point . Thus. V-V, = 0.60 V. III. The current into point cis always a fixed multiple of the current into point b, so lc = IB. where >> 1 is a parameter characteristic of the transistor. Use these rules to answer the questions What is the potential V... in terms of V., in the limit 800? (Hint: Determine If in terms of , and use this to determine Ic in terms of V.. and 8. The polential difference across the 1.0 kn resistor can then be used to determine Vou Take the limit 8 + 50 in this result.) Express your answer in terms of Vin IVO AL ?
