AC current
DC current
AC voltage
DC voltage

come on
why do people say these?

alternating current current
alternating current voltage
...

kinda doesnt make sense, although I know what they mean

is there any other way of saying these?

Alternating Voltage and Direct Voltage?

It does sound redundant when you say it. I have never noticed before.

I have always considered it as a definition of type then property.

First it is alternating current and we are talking about the current property.
Then it is alternating current and we are talking about the voltage property.

Did you do this on purpose?

It is confusing

AC, how do you say that in terms of voltage?

Even when saying it in terms of current, most of the times you end up saying current twice "alternating current current"

still confusing to me :S

AC and DC are words in themselves. That is how you need to look at it, not as initials.

Read a book , ' Electricity ' by Dr Robert Ferguson , printed 1873 ,
At that time you had .....
Direct current = +
Inverse current = -
You can read a google version on the net but the hard copy is pretty cool
interesting to look at pioneer work minus Tesla and Edison

Pet peaves...
While you're at it...

1500 milli-amp battery, instead of mill-amp-hour
RPM per minute (kinda like AC current)
(actually RPM/min is a measure of rotational acceleration, like ω/(s^2), but not velocity)
RPMs, whenever it is greater than 1 (if anything it would be RsPM)
Pounds of torque, instead of ft-pounds
Things like 100 buildings per mile, instead of square mile
Using light-year like it is a measure of TIME! It's not.

on and on...
