The collector current is 10 mA in n-p-n transistor. If 80% electrons ...
The given information:
The collector current in an n-p-n transistor is 10 mA.
80% of the emitted electrons reach the collector.
Understanding the concept:
In an n-p-n transistor, the emitter current (Ie) is the sum of the base current (Ib) and the collector current (Ic).
Ie = Ib + Ic
Solution:
To find the emitter current, we need to determine the base current first using the given information.
Step 1: Calculating the collector current (Ic):
Given that the collector current is 10 mA.
Step 2: Calculating the emitter current (Ie):
Since 80% of the emitted electrons reach the collector, the total emitted current (Itotal) is given by:
Itotal = (Ic / 0.8)
Therefore, the emitter current (Ie) is given by:
Ie = Itotal = (Ic / 0.8)
Step 3: Calculating the base current (Ib):
Using the equation Ie = Ib + Ic, we can rearrange it to find Ib:
Ib = Ie - Ic
Substituting the values of Ie and Ic, we get:
Ib = (Ic / 0.8) - Ic
= Ic * (1/0.8 - 1)
= Ic * (1/0.8 - 0.8/0.8)
= Ic * (1 - 0.8) / 0.8
= Ic * 0.2 / 0.8
= Ic / 4
Step 4: Calculating the base current (Ib) using the given collector current (Ic):
Substituting the value of Ic (10 mA) into the equation for Ib, we get:
Ib = 10 mA / 4
= 2.5 mA
Hence, the base current (Ib) is 2.5 mA.
Step 5: Calculating the emitter current (Ie) using the calculated base current (Ib):
Substituting the value of Ib (2.5 mA) into the equation for Ie, we get:
Ie = (10 mA / 0.8)
= 12.5 mA
Therefore, the correct answer is option 'B': The emitter current will be 12.5 mA.
The collector current in an n-p-n transistor is 10 mA.
80% of the emitted electrons reach the collector.
Understanding the concept:
In an n-p-n transistor, the emitter current (Ie) is the sum of the base current (Ib) and the collector current (Ic).
Ie = Ib + Ic
Solution:
To find the emitter current, we need to determine the base current first using the given information.
Step 1: Calculating the collector current (Ic):
Given that the collector current is 10 mA.
Step 2: Calculating the emitter current (Ie):
Since 80% of the emitted electrons reach the collector, the total emitted current (Itotal) is given by:
Itotal = (Ic / 0.8)
Therefore, the emitter current (Ie) is given by:
Ie = Itotal = (Ic / 0.8)
Step 3: Calculating the base current (Ib):
Using the equation Ie = Ib + Ic, we can rearrange it to find Ib:
Ib = Ie - Ic
Substituting the values of Ie and Ic, we get:
Ib = (Ic / 0.8) - Ic
= Ic * (1/0.8 - 1)
= Ic * (1/0.8 - 0.8/0.8)
= Ic * (1 - 0.8) / 0.8
= Ic * 0.2 / 0.8
= Ic / 4
Step 4: Calculating the base current (Ib) using the given collector current (Ic):
Substituting the value of Ic (10 mA) into the equation for Ib, we get:
Ib = 10 mA / 4
= 2.5 mA
Hence, the base current (Ib) is 2.5 mA.
Step 5: Calculating the emitter current (Ie) using the calculated base current (Ib):
Substituting the value of Ib (2.5 mA) into the equation for Ie, we get:
Ie = (10 mA / 0.8)
= 12.5 mA
Therefore, the correct answer is option 'B': The emitter current will be 12.5 mA.

Here, IC = 80% of IE
Hence, IC = 80 / 100IE
