Given:
Ratio of collector current to emitter current (Ic/Ie) = 0.96

To find:
Current gain of the amplifier

Solution:
The current gain of a common emitter transistor amplifier is given by the formula:

β = Ic / Ie

Where β is the current gain, Ic is the collector current, and Ie is the emitter current.

Given that Ic / Ie = 0.96, we can substitute this value into the formula to find the current gain:

β = 0.96

Since we need to find the current gain, we can solve for β:

β = Ic / Ie = 0.96

Calculation:

To find the current gain, we can rearrange the formula:

β = Ic / Ie

Multiply both sides by Ie:

β * Ie = Ic

Rearrange the equation to solve for Ic:

Ic = β * Ie

Substituting the given value of β = 0.96:

Ic = 0.96 * Ie

Therefore, the current gain of the amplifier is 0.96.

Conclusion:
The current gain of the amplifier is 0.96.
