7.35 An npn BJT with grounded emitter is operated with V BE = 0.700 V, at which the collector current is 0.5 mA. A 5-k resistor connects the collector to a +5-V supply. What is theresulting collector voltageVC?Now, if a signal applied to the base raises v BE to 705 mV, find the resulting total collector current i C and total collector voltage vC using the exponential i C–vBE relationship. For this situation, what are vbe and vc? Calculate the voltage gain vc/vbe. Compare with the value obtained using the small-signal approximation, that is, –gmRC
