UNIT-1 ELECTROSTATICS Where the energy of capacitor does resides? Do electrons tend to go to region of low or high potential? What is the net charge on the charged capacitor? A Gaussian surface encloses an electric dipole within it. What is the total flux across sphere? 5. Find the dimension of 1/2εoE2. 6. In a certain l m3 of space‚ electric potential is found to be V Volt throughout. What is the electric field in this Region? 7. If Coulomb law involves 1/r3 instead of 1/r2 dependence‚ would Gauss

supplies. The electrodynamic wattmeter uses the reaction between the magnetic fields of two current-carrying coils‚ one fixed and the other movable. The voltage and current coils are wound around a laminated iron core to produce a magnetic field across the air gap. When the current through the fixed-position field windings is the same as current through the load and the current through the moving coil is proportional to the load voltage‚ then the pointer deflection is proportional to the power (P=IV).

and found in cats worldwide. Nature’s pest‚ the mosquito‚ is the cause of Dirofilaria immitis. At least 70 species of mosquitoes can serve as intermediate hosts‚ of which the most common vectors are Aedes‚ Anopheles‚ and Culex (Woodhaven Labs). When taking a blood meal from microfilaremic host --like wolves‚ coyotes‚ foxes or dogs-- the adult female mosquito becomes infected with the microfilariae that becomes a larva within 10-14 days. The mosquito then deposits this parasite on the surface of the

Monsoon maladies – Enemies in the Rain Monsoon brings with it the much-awaited relief from the long spell of sultry‚ scorching summer. When the season of rains people are all set to enjoy it to the hilt irrespective of their age.

BEDBUGS: PUBLIC HEALTH IMPORTANCE 237 CHAPTER 4 Bedbugs‚ fleas‚ lice‚ ticks and mites Ectoparasites that live on the body‚ in clothing and in beds There are many different species of bloodsucking fleas‚ lice‚ ticks and mites. Lice live on humans or in their clothing‚ while fleas are frequently found taking bloodmeals on people and domestic animals. Bedbugs‚ which can be found in beds or furniture‚ feed on humans to obtain blood-meals. Some mites live in people’s skin‚ e.g. the mites that

Finding the Charge to Mass Ratio of the Electron Via a Uniform Magnetic Field Generated by Helmholtz Coils Abstract The charge to mass ratio of the electron was found to be [pic] with a percent difference from the accepted value ([pic]) of 1.1% when adjusted for the Earth’s magnetic field. Without taking the Earth’s magnetic field into consideration‚ the charge to mass ratio was found to be [pic] with a percent difference of 5.3%.

They are of the simplest design‚ a loop of conducting material. It is used as a transmitter of radiofrequency energy. This receiver coil is placed on the region of interest or the knee‚ in this example‚ for greater magnetic sensitivity. It’s often used because it has a good signal to noise ratio for tissue next to the coil. However

humans and Aedes aegypti or Aedes albopictus mosquito through the transmission of the viruses to humans by the bite of an infected mosquito. The mosquito becomes infected with the Dengue virus when it bites a person who has Dengue and after a week it can transmit the virus while biting a healthy person. Dengue cannot be transmitted or directly spread from person to person. Aedes aegypti is the most common aedes specie which is a domestic‚ day-biting mosquito that prefers to feed on humans.
