A transistor is operating at a reverse bias. Describe the step-by-step process of how a small change in the reverse bias affects the collector current.
💡 Hint: Look at how current varies as you adjust bias.
Under various reverse bias values, derive the relationship of junction proximity to collector current and the resulting implication on transistor function.
💡 Hint: Think about what happens to the spatial profile of carriers.
