If electric resistance is to be decreased, then the number of resistances should be connected in – (1) Series (2) Parallel (3) Mixed arrangement (4) None of these

1 Answer

Answer :

(2) Parallel Explanation: Resistors are in parallel when each resistor is connected directly to the voltage source by connecting wires having riegligible resistance. Each resistor thus has the full voltage of the source applied to it. When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst them
