Give Eqn for Current relating it to Q.

What is it measured in

charge per time
measured in amperes
What is Ohm's Law?

What is a the requirement for applying Ohms's Law?
V=IR

R is must be constant and V can vary
What is Joule's Heating Law and what unit does it give?
P=I^2 R

P=IV

P measured in Watts; Amp^2*Ohms
Give Vrms and Irms eqns

When are they used
Vmax/(2)^.5

Imax/(2)^.5

For power calculations of AC circuits
Give eqn for avg power of AC circuit
Pavg=Irms*Vrms

Because the current constantly flips
