The Total solution for NCERT class 6-12
(a) Threeresistors 2Ω, 4Ω and 5Ω are combined in parallel. What is the total resistanceof the combination?(b) If the combination is connected to a battery of emf 20 V andnegligible internal resistance. Determine the current through each resistor,and the total current drawn from the battery.
