+5V V control : 0V = light on 5V = light off light bulb 50 R HW5, PHYSICS 127A 2010 1. The following circuit is a lightbulb driver using a PNP transistor. Calculate R needed to drive the light bulb assuming β = 100. Don’t forget the engineering margin for β . This symbol represents 0 volts This symbol represents connecting to a +5 V battery +10 V 4k 2. (a) For the following circuit, plot as a function of Vin (from -2 to +3 volts) the base current, collector current, and Vout. (b) Compute the
