The output characteristics of a transistor are shown in the figure. When is and , then the value of is ________.
Step 1: Given data
Value of =
Current
Step 2: Formula used
The which is a current gain can be computed using the following formula:
Step 3: Compute the
To determine the , choose any two values of input current from the graph. We select and . So,
And the corresponding output currents are and respectively. So,
Therefore, the is,
Hence, the value of will be .
