A transistor has a current gain β = 100. The base current is 50 μA. The collector current is:
A Zener diode with breakdown voltage 5.6 V is used as a voltage regulator. If the input voltage varies between 7 V and 10 V and the Zener current must not exceed 100 mA, the maximum value of the series resistor R is:
A logic circuit has two inputs A and B and output Y = AB + A'B'. The circuit is equivalent to:
A NAND gate is equivalent to:
A transistor amplifier has voltage gain of 100. If the input resistance is 1 kΩ and load resistance is 5 kΩ, the power gain is:
A transistor is connected in common-emitter configuration with collector supply V_CC = 10V, collector resistance R_C = 1 k ohm, and beta = 100. If the base current is increased from 10 μA to 20 μA, the change in collector-emitter voltage is:
In a logic circuit, the output of a NOR gate is fed into a NOT gate. The equivalent single gate is:
A transistor in common emitter configuration has a current gain β = 100. If the base current changes by 10 μA, the change in collector current is:
