In the AC circuit shown in the figure below, R = 70.0 \(\Omega\) and the output voltage of the AC source is \(\Delta V_{max} \sin(\omega t)\).
\(\Delta V_{max} \sin \omega t\)
R
(a) If \(\Delta V_R = 0.245 \Delta V_{max}\) for the first time at t = 0.0095 s, what is the angular frequency of the source?
rad/s
(b) What is the next value of t for which \(\Delta V_R = 0.245 \Delta V_{max}\)?
s

When an inductor is connected to a 60.0 Hz source it has an inductive reactance of 54.6 \(\Omega\). Determine the maximum current in the inductor (in A) if it is connected to a 47.0 Hz source that produces a 100 V rms voltage.
