In a transistor amplifier, when the signal changes by 0.04 V, the base current changes by and collector current by 2 mA. If collector load and. Then find the voltage gain
The value of the resistor, , needed in the dc voltage regulator circuit shown here, equals:
Which of the following statements is incorrect regarding the working of a transistor?
When a transistor is connected in common base mode, the current gain is found to be α = 0.98 and the reverse saturation current for the collector-base junction is found to be 0.6 𝜇𝐴. On connecting the same transistor in common-emitter mode as an amplifier the base current is found to be 20 𝜇𝐴, the magnitude of the collector current in this case is
This circuit in figure represents which LOGIC Gate
Mobilities of electrons and holes in a sample of intrinsic germanium a room temperature are 0.36m2V-1s-1 and 0.17m2V-1s-1 . The electron and hole densities are each equal to 2.5×1019m3. The electrical conductivity of germanium is
