An important concept to aid understanding of electromagnetics is electrical length. Electrical length is a unitless measure that refers to the length of a wire or device at a certain frequency ration of the physical impedance electrically example, consider a 1-meter long antenna. At 1kHz this antenna has an electrical length of about of of the device to the || 10^(-6) A long at 10^(-6). An equivalent way to say this is in units of wavelength; that is, a 1 meter antenna is and is considered electrically It is defined as the of the signal frequency: As an kHz. At length is less than about 1/20 can be considered electrically short. However, at 100MHz, the frequency of FM radio, this antenna has an electrical length kHz this antenna is In general, any device whose electrical An important concept to aid understanding of electromagnetics is electrical length.
