Buffer
A buffer is a logic circuit that amplifies the current or power. Basically it is used change the driving capability of a logical circuit. Therefore it is sometimes referred as drive. A simple buffer and tri state buffers (active high and active and low ) are shown in figure.
A tri state buffer if enabled provided the same logic level of the output as that of input i ,e if input is at logic 1 then it provides logic 1 output.

Successive-approximation analog to digital converter This converter, shown in Figure, also contains a D/A converter, but the binary counter is replaced by a successive-approxim
Q. With a direct current of I A, the power expended as heat in a resistor of Ris constant, independent of time, and equal to I 2 R. Consider Problem and find in each case the effe
In practice, it is usually better to wind the field coils on the rotor and supply the field current to them via slip rings. As the rotor turns, the changing magnetic field expe
The force between two wires 1 metre apart and each carrying 1 amp is 2 x 10 -7 Newtons when in a vacuum (or in practice, air).However, it is found experimentally that the force is
