A) 75
B) 100
C) 150
D) 50
Correct Answer: D
Solution :
For a transistor |
\[{{I}_{E}}={{I}_{B}}+{{I}_{C}}\] |
where \[{{I}_{E}}=\] emitter current |
\[{{I}_{B}}=\] base current |
\[{{I}_{C}}=\] collector current |
and current gain \[\beta =\frac{\Delta {{I}_{C}}}{\Delta {{I}_{B}}}\] |
\[\Delta {{I}_{C}}=5\times {{10}^{-3}}\,A\] |
\[\Delta {{I}_{B}}=100\times {{10}^{-6}}\,A\] |
\[\beta =\frac{5}{100}\times 1000=50\] |
