" When cells are connected in parallel,then "

Assertion : When cells are connected in parallel to the external load, the effective emf increases reason: All the cell will be sending the current to the external load in the same direction

Statement- 1 : When cells are connected in parallel to the external load, the effective emf increases Statement-2 : All the cell will be sending the current to the external load in the same direction

Statement- 1 : When cells are connected in parallel to the external load, the effective emf increases Statement-2 : All the cell will be sending the current to the external load in the same direction

A galvanometer together with an unkonwn resistance in series is connected across two identical cells, each of emf 1.5 V. When the cells are connected inseries, the galvanometer records a current of 1 A and when the cells are connected in parallel, the current =0.6 A. What is the internal resistance of each cell ?

An equiring physics student connects a cell to a circuit and measures the current drawn from the cell to I_1 . When he joins a second identical cell is series with the first, the current becomes I_2 . When the cells are connected in parallel, the current through the circuit is I_2 . When the cells are connected are in parallel, the current through the circuit is I_3 . Show that relation between the current is 3I_3 I_2 =2I_1(I_2 + I_3).

When cells are connected in parallel, what will be the effect on (i) current capacity (ii)e.m.f. of the cells

The emf of a dry cell is 1.5 V , when an ammeter and a resistance are connected with the series combination of two dry cells in series,then the ammeter reads 1A,and when the cells are connected in parallel the reading of the ammeter becomes 0.75A What is the internal resistance of the dry cell? Draw the circuit diagrams?

If three cell are connected in parallel then equivalent emf……. and equivalent internal resistance is …..

If three cell are connected in parallel then equivalent emf……. and equivalent internal resistance is …..

Three cells each of emf 1.5 V, after being connected in series with each other, are connected to the ends of a resistance. The current obtained is 1 A. When the cells are connected in parallel across the ends of the same resistance, the current is found to be 0.36 A. Find the external resistance and the internal resistance of each cell.
