A voltage wave v = 10 + 20 sin ωt + 7.5 sin 3 ω(t) is applied to a series combination of two elements. The current is i = 5 sin (ωt + 20°) + 1.5 sin (3ωt + 10°). The elements are-A-R and CB-R and LC-L and CD-both inductances-A-R and C

Question

A voltage wave v = 10 + 20 sin &omega;t + 7.5 sin 3 &omega;(t) is applied to a series combination of two elements. The current is i = 5 sin (&omega;t + 20&deg;) + 1.5 sin (3&omega;t + 10&deg;). The elements are-A-R and CB-R and LC-L and CD-both inductances-A-R and C

APTITUDE CRACK · Accepted Answer

A R and C DC component is absent in current and current is leading the voltage. Hence R and C.
