An alternating current, measured in amperes (A), is represented by the equation: $I=5.0\sin \left(120\mathrm{\pi t}\right)$. Sketch a graph to represent the current.

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.

The Y-sensitivity and time-base settings are $5 \mathrm{V}/\mathrm{cm}$ and $10\mathrm{ms}/\mathrm{cm}$. The trace seen on the $\mathrm{CRO}$ screen is the one shown in Figure .

Determine the amplitude, period and frequency of the signal applied to the $\mathrm{Y}$-input of the $\mathrm{CRO}$.
