Question

2 For the sine wave below in Figure 1, dewesise the peak, peak to peak, rms and Figure I 3. A simusoidal voltage is applied to the resistive cireuit in Figure 2 as below. Determine () i (d) Ipo (e) at the positive peak ()b)1 Figure 2 Determine the frequency and time period for the angular velocity 1256 rad/s? Sine wave A has a positive going zero crossing สเ 0°. Sine wave B has a positive zero crossing at 20P. Determine the phase angle between the two signals. Which leads?

Answer 1

2.Ans)

$\mathbf{V_{peak}=25\: \: V}$

$V_{peak-peak}=25-(25)=50\: \: V$

$\mathbf{V_{peak-peak}=50\: \: V}$

$V_{RMS}=\frac{V_{peak}}{\sqrt{3}}=\frac{25}{\sqrt{2}}=17.68\: \: V$

$\mathbf{V_{RMS}=17.68\: \: V}$

$V_{Avg}=\frac{2V_{peak}}{\pi }=\frac{2*25}{\pi }=15.91\: \: V$

$\mathbf{V_{Avg}=15.91\: \: V}$
