Hi all, I'm stucked in this prob. , the only problem is how can I convert 5+5cos(2000(pi)t) to phasor form, obviously there is no phase but what is the magnitude?:confused:

I'm going to take a guess here as I've just started on phasors in physics but it would be 5, as that is the multiple for the cos(x) function - either that, or it is 10, because of the add.

K, it's been a while since e-fundies, but I believe the answer is because the first 5 being added is a DC offset. Therefore, it's rather irrelevant as far as AC formulas and equations are concerned and can be left off.

But look it up to be sure ;)
