A direct current of 2 A and an alternating current having a maximum value of 2 A flow through two identical resistances. The ratio of heat produced in the two resistances will beA. 0.042361111111111B. 0.043055555555556C. 0.084027777777778D. 0.16736111111111

Answer» Correct Answer - C
`underset(DC)(H) / underset(DC)(H) = ( underset(DC)(i)/underset(rms)(i))^(2) (sinceH proptoi^(2) = 2/sqrt 2)^(2) = 2`
