In a transistor, the base current is \(10 \mu \mathrm{A}\) and the emitter current is \(1 \mathrm{~mA}\), then the collector current is
- A \(990 \mu \mathrm{A}\)
- B \(100 \mu \mathrm{A}\)
- C \(1010 \mu \mathrm{A}\)
- D \(90 \mu \mathrm{A}\)
Answer & Solution
Correct Answer
(A) \(990 \mu \mathrm{A}\)
Step-by-step Solution
Detailed explanation
Base current, \(i_B=10 \times 10^{-6} \mathrm{~A}=10 \mu \mathrm{A}\) Emitter current, \(\mathrm{i}_{\mathrm{E}}=1 \times 10^{-3} \mathrm{~A}=1000 \mu \mathrm{A}\) \(\mathrm{i}_{\mathrm{E}}=\mathrm{i}_{\mathrm{B}}+\mathrm{i}_{\mathrm{C}}\) Collector current…
