Question
Write an expression for an alternating emf that varies sinusoidally with time. Show graphically variation of emf with time.
✓
Answer
An alternating emf that varies sinusoidally with time is given by $e=e_0 \sin \omega t$, where $e_0$ is the maximum value of the emf, called the peak value, and co is the angular frequency of the emf. $\omega=2 \pi f=\frac{2 \pi}{T}$, where $f$ is the frequency of the emf, expressed in $Hz$, and $T$ is the periodic time of the emf expressed in second.
Using these data, we can plot e versus t
