Common dime-store cells and batteries
The cells you see in the grocery, department, drug, and hardware stores which are popular for use in household convenience items such as flashlights and transistor radios are of the zinc-carbon variety. These gives 1.5 V and are available in sizes known as AAA (very small), AA, C, and D. You have probably seen all of these sizes hanging in the packages on the pegboard. Batteries made from these cells are generally 6 V or 9 V.
One type of cell and battery which has become available recently is the nickel cadmium rechargeable type.
What is a fiber optic sensor? Fiber optic sensor: A fiber optic sensor is a sensor which uses optical fiber either like the sensing tool ("intrinsic sensors"), or implies as
The percentage of carbon in mild steel is (A) 0.08 to 0.3 % (B) 0.5 to 1.4 % (C) 2.35 % (D) 0.5 % Ans: The percentage of carbon in mild st
A parallel plate capacitor has plates of area 200 cm 2 and separation among the plates 1.00 mm. What potential difference will be manufactured if the charge of 1 nC is given to th
Weber; Wb (after W. Weber, 1804-1891): The derived SI unit of magnetic flux equivalent to the flux that, relating a circuit of one turn, generates in it an electromotive force
a) Explain ampere's law and calculate magnetic field at any point P beacuse of (i) Infinite long wire (ii) Inside a solenoid (iii) Inside a toroid b) Explain Biot S
It is the force that the field would exert on any unit magnetic pole placed in the field. It is also known as magnetic force.
Light coupling: Another way to look at light guiding in a fibre is to measure the fibre's acceptance angle. This angle is the angle within which the light should enter the fib
It describes the behaviour of a collection of a particle N(E) with gives energy through N(E)α exp(-E/KT) where K is Boltzmann constant. It can be explained as a collection of
Faraday's second law of electrolysis: The charge Q needed to deposit or liberate a mass m is proportional to the charge z of the mass, the ion and inversely proportional to th
Determine the working of N- Channel JFET In N-channel JFET, two p regions are connected with each other (internally or externally) and are called gate (G). Ohmic contacts are
