For a transistor to act as a switch, it must be operated in
Identify the correct Logic Gate for the following output (Y) of two inputs A and B.
The positive feedback is required by an amplifier to act an oscillator. The feedback here means :
The I-V characteristics of a p-n junction diode in forward bias is shown in the figure. The ratio of dynamic resistance, corresponding to forward bias voltage of 2 V and 4 V respectively, is :
