AC Power

Question 1

What is the voltage in a capacitor/inductor?

Answer 1

V(t)=V0 cos(ωt)

Question 2

What is the current in a capacitor/inductor?

Answer 2

I(t)=I0 sin(ωt)

Question 3

What is the average power for a capacitor/inductor?

Answer 3

<p>=1/T ∫Pdt from 0 to T
</p>

Question 4

What is the root mean squared current?

Answer 4

I_rms=I0/(2)^1/2

Question 5

What is the root mean squared voltage?

Answer 5

V_rms=V0/(2)^1/2

Question 6

What is the average power involving the root mean squared?

Answer 6

<p>=(V_rms)^2/R
</p>

Question 7

What is the average power dissipation?

Answer 7

<p>=V_0 I_0 cosϕ /2
