Question

the βdc of a transistor is its
select one:
o a. power gain
o b. current gain
o c. voltage gain
o d. internal resistance

Explanation:

In transistor theory, \( \beta_{\text{DC}} \) (also known as \( h_{FE} \)) represents the direct - current current gain of a transistor. It is defined as the ratio of the collector current (\( I_C \)) to the base current (\( I_B \)) in a transistor, i.e., \( \beta_{\text{DC}}=\frac{I_C}{I_B} \). Power gain is related to the product of current gain and voltage gain, voltage gain is related to the ratio of output voltage to input voltage, and internal resistance is a different parameter related to the transistor's internal impedance characteristics. So \( \beta_{\text{DC}} \) is the current gain of the transistor.

Answer:

b. current gain
