Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer surfaces oboth shells.
Ans) THE charge on outer surface of A will be 2q and outer surface of B will be zero due to earthing charge on b will flow to earth.
Determine the change in entropy, in joules, when 5 moles of an ideal gas expands from a value of 4 lits. to 40 lits. at 27°C. (R = 8.314 JK -1 mol -1 )
Two students, A and B, living in neighbouring college rooms, decided to economise by connecting their ceiling lights in series. They agreed that each would install a 100-W bulb
Voltages relative to earth It is very common in electrical circuits to have an earth connection. This earth connection has no effect on potential differences across components
The Josephson effect is a term given to the phenomenon of current flow across two superconductors separated by a very, thin insulating barrier. This arrangement, two superconductor
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
Their resistivity is very low and temperature coefficient of resistance is not constant. These are materials with unfilled or overlapping energy bands. Current carriers here are fr

CELL CAPACITY The amount of electrical energy that a cell can provide from new to the end of its useful voltage on load is called the cell capacity and is quoted in Ampere hour
The liquid calculates milliliter, mL, is the same as 1 cm 3 . How many milliliters of liquid can be held in a 2.5-m 3 container?
Thermonuclear reactions: The fusion reactions which require extremely high temperatures are called thermonuclear reactions. The most important thermonuclear reactions take plac
