Hot wire ammeters are used for measuring

An alternating current at any instant is given by $i = [6 + \sqrt{56} \sin (100 \pi t + \frac{\pi}{3})] \ A$. The rms value of the current is . . . . . . . (in $A$)

For a domestic $AC$ supply of $220 \,V$ at $50 \,cps$,the potential difference between the terminals of a two-pin electric outlet in a room is (in volt) given by

The variation of the instantaneous current $(I)$ and the instantaneous emf $(E)$ in a circuit is as shown in the figure. Which of the following statements is correct?

If ${E_0}$ represents the peak value of the voltage in an ac circuit,the r.m.s. value of the voltage will be

The output voltage of a step-down transformer is measured to be $24 \text{ V}$, when connected to a $12 \text{ W}$ light bulb. The value of the peak current is . . . . . . .
