While a collector to emitter voltage is constant in a transistor, the collector current changes by 8.2 mA when the emitter current changes by 8.3 mA. The value of forward current ratio is

Options

A. 82
B. 83
C. 8.2
D. 8.3

Answer

A

Explanation

Given that,
In a transistor,
The change in collector current,
`Delta I_(C) = 8.2 mA`
The change in emitter current, `Delta I_(E) = 8.3 mA`
The value of forward current ratio,
`Delta I_(C)/Delta I_(b) = Delta I_(C)/Delta I_(E)-Delta I_(C) = 8.2/8.3-8.2 = 2`
