## What is normal electric field?

The strength of the earth’s natural electric field varies, but on average is about **one-thousandth of a volt per meter**. Electric field strength typically varies from 10 to 150 volts per meter under electric distribution lines and 5 to 100 volts per meter inside homes and workplaces.

## What is PEC boundary condition?

PEC boundary conditions are **used to specify boundaries that behave as a Perfect Electric**. **Conductor such as metals**. For such a boundary, the component of the electric field parallel to the boundary is. zero. The component of the magnetic field perpendicular to the boundary is also zero.

## Why are tangential electric fields equal?

That is, the **tangential Electric Field will always be zero on a metal surface**. This is because the free charge will swim around and cancel it out, simply by the attractive nature of charge.

## What are boundary conditions for electric field?

Boundary condition on normal component of electric field:

If **there is only a volume charge density, the right hand side would be zero**, since the volume of the box is infinitely small. However, there can be a surface charge density on the surface of the con- ductor.

## What are the conditions of perfect electric conductor Pec?

Properties of perfect conductors

Perfect conductors: **have exactly zero electrical resistance** – a steady current within a perfect conductor will flow without losing energy to resistance. Resistance is what causes heating in conductors, thus a perfect conductor will generate no heat.

## What is PEC in HFSS?

The **Perfect Electric Conductor** or PEC Boundary is the HFSS default boundary that is applied to all outer faces of the solution space. It represents a lossless perfect conductor. … This boundary can also be used to create a symmetry plane if it is placed on an outer face of the solution space.

## What is meant by electric field intensity?

**A measure of the force exerted by one charged body on another**. The electric field intensity (volts/meter) at any location is the force (Newtons) that would be experienced by unit test charge (Coulombs) placed at the location. …

## How do you find the tangential component of an electric field?

∮**Loop→E⋅d→L=Et1dL−Et2dL**. or in other words the tangential components of →E must be continuous across the surface SS. Since SS is an arbitrary surface it follows that the tangential components of the electric field must be continuous across any surface.
