Which is the correct way to connect batteries in series .

What are the advantages of connecting electrical devices in parallel with the battery instead of connected them in series ?

12 cells each having the same emf are connected in series and are kept in a closed box. Some of the cells are wrongly connected. This battery is connected in series with an ammeter and two similar cells . The current is 3A when the two cells aid the battery and is 2A when the cells and the battery oppose each other. How many cells in the battery are wrongly connected?

A parallel combination of an 8 Omega resistor and an unknown resistor R is connected in series with a 16 Omega resistor and a battery. This circuit is then disassembled, and the three resistors are then connected in series with each other oand the same battery. in both arrangements, the current through the 8 Omega resistor is the same. What is the unknown resistance R?

Assertion : Two identical bulbs when connected across a battery, produce a total power P. When they are connected across the same battery in series total power consumed will be (P)/(4) . Reason : In parallel, P=P_(1)+P_(2) and in series P=(P_(1)P_(2))/(P_(1)+P_(2))

Twelve cells each having the same emf are connected in series and are kept in a closed box. Some of the cells are wrongly connected. This battery of cells is connected in series with an ammeter and two cells identical with the others. The current is 3A when the cells and the battery aid each other and is 2A when the cells and the battery oppose each other. How many cells in the batter are wrongly connected?

Draw a circuit diagram when three bulbs are connected in series with a battery of cells, which are also connected in series.

A galvanometer, together with an unknown resistance in series, is connected across two identical batteries of each 1.5 V . When the batteries are connected in series,the galvanometer records a current of 1 A , and when the batteries are connected in parallel, the current is 0.6 A . In this case, the internal resistance of the battery is

Which electrical elements are connected in series ?

Twelve cells each having the same e.m.f are connected in series and are kept to a closed box. Some of the cell are connected in reverse order .The battery is connected in series with an ammeter an external resistance R and two cells of the same type as an in the battery .The current when they and support each other is 3 ampere and current is 2 ampare when the two oppose each other. How many cells are connected in reverse order ?

Two identical p-n junctions may be connected in series in which a battery in three ways , fig . The potential drops across the two p - n junctions are equal in
