• q=w*t
• w=2*p*f
• v=v_m*sin(q+f)
• I=I_m*sin(q+f)
• P_m=I_m*v_m
• P=P_m*sin²(q+f)
• P_effective=P_average=P_m/2
• I_rms=I_{root_mean_squer}=I_m/SQRT(2)

NOTE_Math
P_average=P_m/2
1. P_average=(1/2p)∫₀^p[P_m*sin²(q)]d(q)
2. sin²q=[1/2-cos2q/2]
3. ∫₀^2psin²qdq=∫₀^p[1/2-cos2q/2]d(q)
4. ∫₀^2p[1/2]d(q)=[q/2]₀^p=[(2p)/2-(0/2)]=p
5. ∫₀^2pcos2qdq=(1/2)∫₀^2pcos2qdq
6. ∫₀^2pcos2qdq=(1/2)[sin2q]₀^2p=(1/2)[sin4p-sin0]=0
7. P_average=P_m*(1/2p)*[p-0]=1/2=P_m/2
