Electric Circuits A certain network consists of large number of ideal linear resistances, one of which is designated as R and two constant ideal source. The power consumed by R is P1 when only the first source is active and P2 when only second source is active. In both sources are active simultaneously then the power consumed by R is √P1 ± √P2. P1 ± P2 . (√P1 ± √P2)2. (P1 ± P2 )2. √P1 ± √P2. P1 ± P2 . (√P1 ± √P2)2. (P1 ± P2 )2. ANSWER DOWNLOAD EXAMIANS APP
