WARNING
Transformers are often used to STEP-UP voltage. You may find a low
voltage across the primary and a much higher voltage across the secondary. Use
extreme caution, especially when working around television and other crt high
voltage transformers. They often step voltages up to, or in excess of, 30,000 volts.
BASIC ELECTRONICS FORMULAS
Basic electronics formulas are included to aid you in solving any electronics problem that you may
encounter. These formulas are for antennas, resonance, transistors, vacuum tubes, wavelength, and radar.
Additional formulas may be found in the appropriate NEETS module.
Antennas
An antenna is a conductor or a group of conductors used either for radiating electromagnetic energy
into 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 a
standard or reference antenna. Some antenna formulas are shown below:
