The electrostatic shielding may be found by protecting and enclosing the sensitive instruments inside a hollow conductor due to inside hollow conductors, electric fields is zero.
(i) It is for this reason that it is safer to sit in a car or a bus during lightening rather than to stand under a tree or on the open ground.
(ii) A high voltage generator is usually enclosed in like a cage which is earthen. This would stop the electrostatic field of the generator from spreading out of the cage.
(iii) An earthed conductor also acts as a screen against the electric field. When conductor is not earthed field of the charged body C due to electrostatic induction continues beyond AB. If AB is earthed, induced positive charge neutralizes and the field in the region beyond AB disappears.
Echo vs. Reverberation Sound is a mechanical wave that travels by a medium from a single location to other. This motion by a medium occurs as one particle of the medium interac
Derive the equation of uniformly acceleration motion by analytical method.
An oil pump is drawing 25 kW of electric power while pumping oil with ρ = 860 kg/m 3 at a rate of 0.1 m 3 /s. The inlet and outlet diameters of the pipe are 8 cm and 12 cm, respec
Solar Cells: The solar cells that we see on calculators and satellites are photovoltaic cells or modules (modules are easily a group of cells electrically connected and packaged
It makes sense that copper should be used because it could heat up faster, making the event more efficient.
What is the Ohm Law? Ohm discovered that the amount of current was directly proportional to the voltage (more voltage gives more current) and inversely proportional to the resi
If 10 joules of energy are required to move 5 coulombs of charge between two points, the potential difference between the two points is equal to how many volts? Ans: If 10 j
The differential equation of motion of freely oscillating body is given by 2 d 2 x/dt 2 + 8π 2 x = 0. Evaluate the natural frequency of the body?
why does earth rotate??
Capacitors in parallel: Three capacitors are connected in parallel. If on closing the switch S a current I flows in the circuit, then from Kirchoff's first law:
