WARNINGTransformers are often used to STEP-UP voltage. You may find a lowvoltage across the primary and a much higher voltage across the secondary. Useextreme caution, especially when working around television and other crt highvoltage transformers. They often step voltages up to, or in excess of, 30,000 volts.BASIC ELECTRONICS FORMULASBasic electronics formulas are included to aid you in solving any electronics problem that you mayencounter. These formulas are for antennas, resonance, transistors, vacuum tubes, wavelength, and radar.Additional formulas may be found in the appropriate NEETS module.AntennasAn antenna is a conductor or a group of conductors used either for radiating electromagnetic energyinto space or collecting it from space or both.Antenna gain remains the same for the antenna whether it is transmitting or receiving. Antenna gain(G) can be described as the effectiveness of a directional antenna in a particular direction, compared to astandard or reference antenna. Some antenna formulas are shown below:1-31
