An obliquely incident EM wave cannot transmit or penetrate into a PEC when it is incident.So , you'll only have an incident and a reflected wave.The electric reflection coefficient is -1.

Do oceanic electric fields produce electric currents?
Yes
What is the nature and characteristic of the electric fields?
the nature and characteristic of an electric field
What are the components of electricity?
Electricity is the interaction of many components. These include electric charges, electric fields, electric potentials, electric currents, and electromagnets.
What determines the strength of the magnetic field when current flows through a conductor?
Magnetic fields currently flows through a conductor is determined by multiplying the number of turns of wire by the current flow. This is what causes electricity.
How does an electric generator generate an electric current The generator?
The rotor turns (rotates) causing magnetic fields to move across a coil of wire. This induces an electrical current in the wires of the coil.
When ac passes through a conductor which fields are produced a magnetic field or an electric field?
when ac passes through a conductor, the field produced is an electric field
How do magnets magnetic fields electric currents and metals connect?
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
How do radioactive rays behave in an electric and magnetic field?
That will depend on their electric charge: plus and minus charged rays will behave in opposite ways while uncharged rays will not be affected at all by the fields.
Is gold the best conductor of electric field?
Electric fields are not "conducted", but gold is not the best conductor of electricity per volume, or per mass. Silver has the highest conductivity per mass, and aluminum the highest per volume.
What is the properties of material that is durable and conductor of electricity?
There is no electric field inside a conductor.Otherwise, the charges in the conductor would move.Charges exist only on the surface of a conductor.Otherwise, there would be electric fields inside.All points of a conductor are at the same potential.Since DV=-EDx, since E=0, the potential must be constant.
What form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
Can an electric field be compressed?
Electric fields are similar to magnetic fields, and can be "compressed" by the imposition of other electric or magnetic fields.
What is an edge effect?
My guess is you're referring to the edge effect on electric fields. In many textbooks, and many problems dealing with electric fields you will see assumptions used to minimize the effect an edge has on the electric field you're attempting to analyze, which is done to simplify the problem. One common example is determining the electric field strength at a point a given distance from a conductor carrying X amount of current. It's often assumed that this is an infinitely long conductor. This removes the need to analyze the electric field due to the corner of the conductor, where the shape, sharpness of the corner, size, type of conductor, and amount of current can impact the actual effect that corner has on the electric field strength at a given distance from the conductor. Usually the impact of the corner is minor, so it can be ignored by assuming an infinite conductor. Other examples: -calculating the electric field X distance from a charged plate (assume the plate is infinite)
How are moving electric charges related to electric and magnetic fields?
Moving electric charges create electromagnetic fields.
Can an electric current exert a force on a magnet?
In a conductor - only if the field is moving, thus changing.
What is the difference between positive and negative electric fields?
Positive electric fields attract negative charges while negative electric fields attract positive charges.
Which form of energy does not require matter for traveling through space?
Electromagnetic radiation. Energy can also be transmitted by electric fields, by magnetic fields, and by gravitation.Electromagnetic radiation.
