(a) Three resistor `1Omega ,2Omega, and 3Omega` are combined in series. What is the total resistance of the ombination ?
(b) If the combination is connected to a battery of emf 12 V and negligible internal resistance, obtain the potential drop across each resistor.

Three resistors 1 Omega, 2 Omega and 3 Omega are combined in series. What is the total resistance of the comination?

(a) Three resistors 2 Omega 4 Omega and 5 Omega are combined in parallel. What is the total resistance of the combination ? (b) If the combination is connected to a bettery of emf 20 V and neglibible internal resistance, determine the current through each resistor, and the total current drawn from the battery.
