Wondering if my answers are correct and if i have the correct equations for the corresponding question
Thanks

 

Why your current and voltage do not have a unit? Maybe if they have a unit, you wouldn't do the error in pd's calculation

As for the phase angle look here:

You need to properly track your units throughout your work. Had you done so you might have caught most of the several mistakes you made as a result of not doing so.

 

One of the most important calculations in any science is Unit Conversions. Especially when dealing with both the English Foot/Pounds and the SI mks/cgs systems.

 

is this better?

 

Just wondering if my answers are correct and if not where have i gone wrong?
Cheers

Hi,

Doesnt look right.

The problem specifies values of R=25 Ohms and C=45uf.

What is the value of the cap, it is 45uf, and how do you convert that to Farads?
In other words, what is 1uf in Farads (then 45 times that amount)?

 

You didn't convert the kΩ value for Xc. You left the k off. And on a personal note, why on earth are you doing the calculations in ink!?!? Nice neat penmanship and sketches though.

Hi,

I would argue the ink vs pencil thing but the photos are very readable unlike many of the stuff i see come through here
Congrats to the OP for the legible photos.
