Total power consumed when two resistors of resistance R are connected in series is P. How much power is consumed when they are connected in parallel ? |

Answer» `(P)/(4)` CONSUMED power is P. when two RESISTORS are CONNECTED in series. Suppose consumed power is `P_(1)` for each `therefore (1)/(P_(1)) + (1)/(P_(1)) = (1)/(P)` (series connection ) `therefore (2)/(P_(1)) = (1)/(p)` `therefore P_(1) = 2 P ` Now power consumed when they are connected in PARALLEL, `therefore P_(2) = P_(1) + P_(1) ` `therefore P_(2) = 2P_(1) ""( "Putting" , P_(1) = 2P)` `therefore P_(2) = 4P` |
