Question

In a common base circuit, if the collector base voltage is changed by $0.6V$, collector current changes by $0.02mA$. The output resistance will be

• A. ${10}^4\Omega$
• B. $2\times {10}^4\Omega$
• C. $3\times {10}^4\Omega$
• D. $4\times {10}^4\Omega$

Answer 1

The correct option is C $3\times {10}^4\Omega$

$R=V/I$
$R=3\times {10}^4\Omega$
