A/C Source across pure resistance

Question 1

Ir=?

Answer 1

Ir=Eo/R Sin(ωt+φ)

Question 2

Vr=?

Answer 2

Vr=Eo Sin(ωt+φ)

Question 3

Io=?
Across pure resistance

Answer 3

Io=Eo/R

Question 4

Irms=?
Across pure resistance

Answer 4

Irms=Io/√2=Eo/√2R=Vrms/R

Question 5

P=?
Power loss across resistance

<Pavg>=?
<p>=?
H=?
Heat loss
</p></Pavg>

Answer 5

P=I^2R=Io^2 Sin^2ωtR

<Pavg>=(Io/√2)^2 R=Irms^2 R
<p>=Irms.Vrms
H=<p>t
</p></p></Pavg>
