Questions
Three equal resistances each of 10 are connected as shown in the fig. The maximum power consumed
by each resistor is 20 W. Then maximum power consumed by the combination is
detailed solution
Correct option is D
We know thatPp=P1+P2 and Ps=P1P2P1+P2Resistances R1 and R2, are connected in parallel. Hence their equivalent power is (20 + 20) = 40 W. Now R3 is it in series and hencePs=20×4020+40=80060=13⋅3WTalk to our academic expert!
