Click For Summary
A right-hand circularly polarized wave features an electric field vector (E) that rotates in the direction of the fingers of the right hand, with the thumb pointing in the direction of wave propagation. In this configuration, the Ey component leads the Ex component by 90 degrees. This relationship is crucial for understanding wave polarization in electromagnetism. The discussion confirms the accuracy of this representation of circular polarization. Understanding these principles is essential for applications in optics and telecommunications.

Concept check:
A Right hand circular polarized wave is having the E vector circulates in the direction of the fingers with the thumb in the direction of wave propagation with its components Ey leading Ex by 90 degrees?

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
