We preceded the unit with a lab; using a light bulb, wire and a 'big' battery, we were to find a few ways on how to light the bulb, and a few ways where we couldn't. We were to illustrate the circuit diagrams in our hand-out booklet on the back page of the lab.
Within the booklet, we were to read pages 5 to 12 and were to do worksheets 44,45 & 46.
The current, I, is measured in C/s and is represented by the unit A, amperes.
Potential Difference, V, is measured in J/C.
Power, P, is measured in J/s and is represent by the Watt, W.
I=q/t V=E/q P=IV E/t=IV
P=(q/t)(E/q)=E/t
P=(1 C/s)(1 J/C)=1 J/s
Please feel free to correct.
