Question

For a common base amplifier, the values of resistance gain and voltage gain are 3000 and 2800 respectively. The current gain will be(a) 1.1(b) 0.98(c) 0.93(d) 0.83

Answer 1

b) 0.98 (confused )

Answer 2

The question is based on the concept of common base amplifier and common collector

Resistance gain = 3000 (Given)

Voltage gain = 2800 (Given)

Thus, the current gain will be described by dividing voltage by resistance.

Current gain = voltage gain/ resistance gain

                    = 2800/3000

                    = 0.93

Hence, the current gain will be option (c) 0.93
