The amplified video signals are amplitude modulated using a suitable r.f. carrier wave in a transmitter called ‘AM' picture transmitter. Similarly, the amplified audio signals are
In the mass spectrograph, two positively charged ions having the similar velocity pass through a slit and enter a uniform magnetic field at right angles to their initial velocities
What are single ends? The extreme fiber optics conductor is farthest from the illuminator. The bit which emits light or the end that lights up.
Q. A transistor is connected in CE configuration. The voltage drop across the load resistance ( Rc) 3 k is 6 V. Find the base current. The current gain α of the transistor is 0.97.
Explain Independence of Vectors Quantities Perpendicular vector quantities are independent of one another. This means that the actions of one vector will not affect the action
Why is it that the frequency of light remains the constant as it undergoes refraction at the interface of two material mediums? Ans) If frequencies are dissimilar in different m
