Q. The correct relation for a triode is
A) $g_{m} = \left| \frac{\mathrm{\Delta}I_{p}}{\mathrm{\Delta}V_{p}} \right|_{V_{g} = constt}$
B) $g_{m} = \left| \frac{\mathrm{\Delta}I_{p}}{\mathrm{\Delta}V_{g}} \right|_{V_{p} = constt}$
C) Both
D) None of these
Explanation
The correct answer is Option B: $g_{m} = \left| \frac{\mathrm{\Delta}I_{p}}{\mathrm{\Delta}V_{g}} \right|_{V_{p} = constt}$.
