Two resistances have lengths in the ratio 1:4 and radius 1:2,specific resistances in ratio 3:1. compare their resistances.Solution)Given lengths l1=1 l2=4Given radius r1=1 r2=2 Given specific resistances Ρ(rho)1=3 Ρ2= 1we know the R=Ρl/A R1/R2=3/1.
The device which changes chemical energy into electrical energy is called as electric cell. Battery is a host of constant emf but not constant current.
2-Cryogenics Cryogenic is the science of producing and using very low temperature. The study of low temperature effects in biology and medicine is called cryobiology. Low tem
Capacitor have thin conducting plates (usually made of metal) separated by a layer of dielectric, then stacked or rolled to form a compact device. Many types of capacitors are avai
A base of rectangular vessel measures 10cm x 8cm.
Introduction of physics- Physics Essentials Why do most people believe physics is too hard? Most people get hung up by the feeling that they do not 100% totally understand what
describe the principle, construction and working of Michelson Interferometer.
In an electric field a charge (Q) experiences a force F = QE. If charge is positive then force is directed in the direction of field whereas if charge is negative force acts on i
Illustrate which atomic model did Erwin Schrodinger create? Answer:- Schrödinger's wave equation was on the basis of Heisenberg uncertainty principal that the position and
Vector Direction The significance of 'direction' could be seen in the dissimilarity among velocity and speed. In physics, speed is a pure scalar or something along with a magni
Explain the Adding Waves? When two waves come from the same light source, the light waves are coherent, meaning that the phase difference between the waves is constant in time.
