A circuit has a BJT with an emitter current of 8 mA and a collector current of 6 mA. Calculate the base current, current gain (β), and common base current gain (α).
💡 Hint: Use provided equations to isolate each current type and then use the ratios.
If a BJT operates with β = 200 and IB = 0.2 mA, what would be the collector current? Assuming no saturation effects.
💡 Hint: Remember the relationship between IB and IC through current gain.
