Question

A bipolar junction transistor operates with a collector current of 1.3 A and a base current of 50 mA. What will the value of emitter current?
0 1.7A
1.5A
O 1.25 A
1:35 A​

Answer 1

Answer:

1.35 A

Explanation:

value of emitter current = 1.35 A

Answer 2

Given :

Collector current (I$_c$) = 1.3 A

Base current (I$_B$) = 50 mA

To Find :

The value of emitter current

Solution :

Base current (I$_B$) is given in mA, first we need to convert it into A.

I$_B$ = 50 mA = 50 × $10^-^3$ A = 0.05 A

The relation between emitter, base and collector current is -

⇒   Emitter current (I$_E$) = Collector current (I$_c$) + Base current (I$_B$)

⇒      Emitter current (I$_E$) =  1.3 + 0.05

∴       Emitter current (I$_E$) = 1.35 A

Therefore, the value of emitter current is 1.35 A

So the correct option is (D) 1.35 A
