Linda,
There is a method to the madness, even though it doesn't make studying
any easier.
The "E" stands for "electro motive force" which is measured in volts,
and we commonly refer to it as voltage.
I think the "I" for current comes from some French spelling of
"intensity" and is measured in amperes.
Some of the no brainers are "R" for resistance, "P" for power, and "C"
for capacitance. When you get all that figured out, you will learn that
"Z" stands for impedance, and you will chuck the book out the window.
73, good luck, Steve KW3A
