Experienced Physics Teacher for Physics Tutoring See tutors like this V(x,y,z) = electric potential as a function of x,y, and z E(x,y,z) = electric field vector as a function of x,y, and z E = -∇V = -[(∂V/∂x)i + (∂V/∂y)j + (∂V...
Why is the electric field inside a conductor zero? How does the electric field become zero in a conductor? What is meant by irrotational vector field? What is mean by electric constant? Explain including equation. What is electric field lines?
The Fresnel Equations are a complex equation that means it considers the magnitude and phase both. The Fresnel Equations represents in terms of the electromagnetic field complex amplitude that consider the phase besides power. These equations are the ratios of an electromagnetic field and it makes in...
What is the equation for finding surface area?Answer and Explanation: It depends entirely on the shape that you are trying to find the surface area of. For a cube, simply add up the areas of each side: http://study.com/academy/lesson/how-to-find-the-surface-area-of-a-cube.html For...
This is the magnetic version of the electric equation above. This states that magnet field lines never begin or end. Instead, they must always form closed loops. Ifsomehowmagnetic monopoles(“magnetic charges”) existed, then this equation would look exactly like (i). However, ...
In summary, the conversation discusses finding the electric field at a distance (b) from a rod with a charge of -3.2 micro-coulombs spread evenly throughout its length (a). The student uses the equation E = kq/r^2 and integrates using the charge density to solve for the electric field...
Earth’s magnetic field A cross section of Earth’s magnetic field can be represented as a vector field in which the center of Earth is located at the origin and the positive y-axis points in the direction of the magnetic north pole. The equation for this field is = where m is the ma...
Development of the Evans Wave Equation in the Weak-Field Limit: The Electrogravitic Equation The Evans wave equation [1-3] is developed in the weak-field limit to give the Poisson equation and an electrogravitic equation expressing the electric fie... PK Anastasovski,P Carpenter,C Ciubotariu...
Electric Field | Definition, Calculations & Equations from Chapter 12 / Lesson 4 28K Learn about the electric field force and how to measure electric field strength. Understand the electric field equation and how to calculate electric f...
Thus, by using the equation, we get the current flowing through the resistor is . Current Formula 2 (Power and Voltage) The power transferred is the product of supply voltage and electric current. Thus, we get current equals the power divided by voltage. Mathematically, Where stands for amper...
