Vedclass · Answer

(B) The root mean square (r.m.s.) voltage is given as $V_{rms} = 220 \ V$.The relationship between the peak voltage $(V_0)$ and the r.m.s. voltage is $V_0 = \sqrt{2} 	imes V_{rms}$.Substituting the given value: $V_0 = 1.414 	imes 220 \ V$.$V_0 \approx 311 \ V$.Therefore,electrical appliances should be designed to withstand an instantaneous peak voltage of approximately $311 \ V$,which is closest to $310 \ V$ among the given options.

The r.m.s. voltage of domestic electricity supply is $220 \ V$. Electrical appliances should be designed to withstand an instantaneous voltage of......$V$.
