Amplifier is a functioning by which the amplitude of variation of ac signal voltage / current/ power can be enhanced
(i) Principle and circuit diagram: The amplifying action of the triode is based on the fact that small change in grid voltage produces the similar change in the grid voltage as because of a large change in the plate voltage. A circuit for triode as an amplifier
(ii) Working: First of all the mutual characteristic curves of a triode to be used as an amplifier is plotted and the grid potential - Corresponding to the mid-point of straight portion of characteristic curve is noted.
Bending moment : The diagram in created shear forces, but the applied forces also create bending. Consider a section x x' at a distance x measured from end B. Then R B
a car with an initial speed of 24.5 km/hr accelerates at a uniform rate of 0.98 m/s^2 for 5.6sec. find the final speed and displacement of the car during this time.
Ohm's law : The electric current (i) in a conductor is proportional to the potential difference (V) between its ends of a constant temperature (T). Verification: To v
On the planet Newtonia, a simple pendulum having a bob with mass 1.25 kg and a length of 185.0 cm takes 1.42 seconds, when released from rest, to swing through an angle of 12.5 deg
what are the general properties of magnetism
Atoms are particles of elements, substances that could not break down further. In examining atomic structure through, we have to clarify this statement. An atom cannot be broken do

Regard as an electron and a proton at an instant in time to be at a separation of 5 cm from each other. Presume the pair to be totally isolated from its surroundings in the vacuum
Depending upon the penetration power, there are two parts of X-rays Hard X-rays More penetration power More frequency of the order of ≈ 1019 Hz Lesser wavelength range
