What materials exhibit the piezoelectric effect?
What is the relationship between mechanical strain and electric field for the piezoelectric effect?
Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress.
Examples of material exhibiting piezoelectric effect are cane sugar , quartz , topaz , Rochelle salt etc
dV = pdL
p = polarization
dV = developerd volatge across the length due to electric field = E*d
= dielectric constant of the material

When an electric field is applied on a piece of a piezoelectric material, the dimension along the electric field direction will always change but the sign can be different. Is that correct?
Piezoelectricity. If you apply a mechanical force f along a piezoelectric crystal such as quartz, it will develop a polarization po. If you also apply an electric field E, this causes a mechanical deformation. Such devices are used in microphones, speakers, and pressure transducers. For such systems, the energy equation is dU = TdS + fdl + Edpo. (a) Based on the definition G = U − TS − fl − Epo, determine how dG depends on dT, df, and...
What is the relationship between electric field and electric force? When do we use one over the other? Why would we need both?
What is the relationship between the density of the equipotential lines, the density of the electric field lines and the strength of the electric field? (10 points) 8.
This diagram correctly portrays the relationship between a magnetic field (B) and the electric current (I) that creates it. True or False?
5. (20 points) For many dielectric materials, the relationship between the displacement field D and the electric field E in the material is linear and can be represented simply by th equation D-eE, where ε is the permittivity of the medium. Consider now two long, co- axial cylindrical conducting shells separated by such a dielectric (see the cross-sectional figure below). Let the surface charge density on the inner cylinder with radius a be +o, and assume that the charge is...
Can I get the detailed solution? (1) Is there a relationship between the electric field E and magnetic field B of an electromagnetic wave at each point in vacuum? A. No any relationship. B. Yes, E is perpendicular to B and E cB C. Yes, is parallel to B and E cB D. No relationship between E and B in direction but E-cB in magnitude. 2)) A long, closely wound solenoid is physically altered by doubling the number of turns...
To understand the relationship and differences between electric potential and electric potential energy. In this problem we will learn about the relationships between electric force F⃗ , electric field E⃗ , potential energy U, and electric potential V. To understand these concepts, we will first study a system with which you are already familiar: the uniform gravitational field. F⃗ (z) =−mgk^ 1)Now find the gravitational potential energy U(z) of the object when it is at an arbitrary height z. Take...
