Predict how all three transistor currents (IB, IC, and IE) will be affected as a result of the following fault:

a: All three currents stop. Explanation

Explanation

b: Base current unchanged, collector current stops, emitter current decreases to value of base current (IE = IB). Explanation

Explanation

c: All three currents greatly increase, transistor will likely overheat and fail. Explanation

Explanation

d: Base current unchanged, collector current increases slightly (ideally will not change at all!), transistor dissipates more power in the form of heat (may overheat) Explanation
