A complex current wave is given by $i = 5 + 5\, sin\, (100\, \omega t)\, A$. Its average value over one time period is given as.....$A$
$10$
$5$
$\sqrt {50} $
$0$
Give definition and formula of root mean square plot graph of current versus $\omega t$.
In $ac$ circuit when $ac$ ammeter is connected it reads $i$ current if a student uses $dc$ ammeter in place of $ac$ ammeter the reading in the $dc$ ammeter will be:
An $AC$ current is given by $I = I_0 + I_1$ $sin\, wt$ then its $rms$ value will be
The direct current which would give the same heating effect in an equal constant resistance as the current shown in figure, i.e. the $r.m.s.$ current, is.....$A$
An alternating voltage is represented as $E = 20\,sin \,300t.$ The average value of voltage over one cycle will be.......$V$
