What is the basic unit of capacitance?
What is the ability to store energy in a magnetic field called?
What is the basic unit of inductance?
What is the unit of frequency?
What does the abbreviation “RF” refer to?
Radio frequency signals of all types
The resonant frequency of a tuned circuit
The real frequency transmitted as opposed to the apparent frequency
Reflective force in antenna transmission lines
What is a usual name for electromagnetic waves that travel through space?
What is the formula used to calculate electrical power in a DC circuit?
Power (P) equals voltage (E) multiplied by current (I)
Power (P) equals voltage (E) divided by current (I)
Power (P) equals voltage (E) minus current (I)
Power (P) equals voltage (E) plus current (I)
