Ohm's Law At 24HourCB.com
Table Of Definition 

V =  Voltage in volts 
A =  Electric current in amps 
R =  Resistance the opposition of electrical current in ohms 
P =  Power measured in watts 
V = 
A x R  A = 
V / R 
P / A  P / V  
SQRT ( P x R )  SQRT ( P / R )  
R = 
V / A  P = 
V x A 
V² / P  V² / R 

P / A²  A² x R 
For Example: If you're transmitting 4 watts of RF power from a CB transceiver to a 50 ohm Antenna System, how many volts at that antenna feeding terminal? 14.14 Volts = SQRT ( 4 watts x 50 ohms ) How much current is feeding into the antenna terminal? 0.283 Amps = SQRT ( 4 watts / 50 ohms )
