Differences between a voltage balun and a current balun
... feeding; The voltage potentials and antenna currents need to be symmetrical with respect to ground, or 180° out of phase. The advantage of using coaxial cable is best seen when it is routed near tower legs, masts and conductive objects. Local metal does not influence the RF energy inside the shielde ...

... The rotary field created by the stator has a higher speed than rotor revs. The basis of asynchronous motor function is a creation of the rotary magnetic field, which comes from the alternating current passing through the winding of the stator. This magnetic field induces the voltage in the rotor and ...

... transformer. The low internal plate resistance of the 12B4A helps to make the resistance looking back into the cathode quite low (approximately 500 Ohms). This low impedance is the driving point for the primary of the output transformer TR3a. To reduce magnetic saturation of the iron core, para (par ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
