For a base current of 10 μA, what is the value of collector current in common emitter if βdc = 100

 [A]. 10 μA [B]. 100 μA [C]. 1 mA [D]. 10 mA

Explanation:

IC = 10 x 100 μA = 1 mA.

 Tabrej said: (Jun 14, 2015) Here formula is used. Collector current/Base current = Emitter current.

 Pradeep said: (May 27, 2016) Beta = IC/IB. IC = Beta * IB. = 100 * 10uA. = 1mA. Am I right?

 Pavi said: (Oct 19, 2016) Yes, you are right @Pradeep. Beta = IC/IB.

 Kumar said: (May 4, 2017) Yes, right @Pavi and @Pradeep. Beta = Ic/Ib.

 Abhi said: (Aug 7, 2017) Explain detailly.

 Priya said: (Jan 21, 2018) Thank you all.

 Lalshmishree said: (Mar 19, 2018) Thank you for the explanation.

 Sam said: (Jun 20, 2018) What is for α?

 Anomiee said: (Jan 9, 2019) Here how current is converted from micro to mili Ampere? Please explain in detail.

 Suresh Kumar said: (Jan 25, 2019) 100micro amps = 1mA. Then, 1000micro amps = 1mA. (Micro ÷ 1000=milli).

 Thilak said: (Sep 5, 2019) @Sam. α = ie/ic.
