David Sang and Graham Jones Solutions for Chapter: Alternating Currents, Exercise 3: Question

An alternating voltage $\mathrm{V}$, in volt $\left(\mathrm{V}\right)$, is represented by the equation:

$V=300\sin \left(100\mathrm{\pi T}\right)$

(a) Determine the values of $V_0,\omega \& f$ for this alternating voltage.

An alternating voltage $\mathrm{V}$, in volt $\left(\mathrm{V}\right)$, is represented by the equation:

$V=300\sin \left(100\mathrm{\pi T}\right)$

(b) Calculate $\mathrm{V}$ when $\mathrm{t} = 0.002 \mathrm{s}$. (Remember that $100\mathrm{\pi t}$ is in radians when you calculate this.)

An alternating voltage $\mathrm{V}$, in volt $\left(\mathrm{V}\right)$, is represented by the equation $V=300\sin \left(100\mathrm{\pi T}\right)$. Sketch a graph to show two complete cycles of this voltage.
