Hello,
I'm new here and new to the world of electricity in general. I'm currently going through training to work on electronics (Avionics systems) within Aircraft. I'm loving it but I have a lot of difficulty figuring out proper units in equations. I can do the math but making sure the decimal is in the right spot and the unit is correct is where I have difficulty. I was wondering if anyone had any tips and tricks to how they learned and applied it.
An example would be:
How much power does 20mA through a 5kΩ resistor produce?
P= I^2 XR
P= 20^2 X5
P= 2000
P= 2.0 W (I know this is the answer but I have no idea how to get here from 2000)
Thanks!
