Basic Electronic Formulas Used in Radio
Ohm's Law: Current (Amps) = Voltage divided by Resistance (Ohm's)
Ohm's Law: Resistance (Ohm's) = Voltage divided by Current (Amps)
Ohm's Law: Voltage (Volts) = Current (Amps) times Resistance (Ohm's)
Power (Watts) = Current (Amps) times EMF (Volts)
Half-Wave Dipole in Feet (in Air) = 492 divided by Frequency (MHZ)
Half-Wave Dipole in Ft. (end supported) = 468 divided by Freq (MHZ)
Meters = 300 divided by the frequency (MHZ)
