An alternating current of $rms$ value $10 \, A$ is passed through a $12 \, \Omega$ resistor. The maximum potential difference across the resistor is

$A$ standard filament lamp consumes $100\,W$ when connected to $200\,V$ $AC$ mains supply. The peak current through the bulb will be $........\,A$.

An alternating voltage is represented as $E = 20 \sin 300t$. The average value of voltage over one cycle will be ....... $V$.

The variation of $EMF$ with time for four types of generators is shown in the figures. Which amongst them can be called $AC$?

The peak value of an alternating current is $5 \text{ A}$ and frequency is $60 \text{ Hz}$. How long will the current,starting from zero,take to reach the peak value?

An electric current has both $DC$ and $AC$ components. The $DC$ component is $8 \ A$ and the $AC$ component is given as $I = 6 \sin \omega t$. The $rms$ value of the resultant current is . . . . . . (in $A$)
