Question

how can we connect 4cells of 1.5 each to get 3 volt



try including a drawings ​

Answer 1

Answer:

join 2 cells in parallel and other 2 cells in parallel because in parallel voltage will remain the same then join the 2 paralleled cells in series which will add the voltage and output will be the 3volts

Answer 2

To Do :-

• Using four cells of 1.5 V each we need to get 3 Volts . And we need to draw the circuit .

SolutioN :-

Here we need to obtain 3V from four cells of 1.5V each. So we know that when ,

☯️ $\underline{\textsf{\red{ Cells are connected in parallel :- }}}$

• When cells of same voltage are connected in parallel then , the net voltage is equal to the voltage of each cell .

☯️ $\underline{\textsf{\red{ Cells are connected in series :- }}}$

• When cells of different voltages are connected in series then the net voltage is equal to the sum of individual voltages .

$\rule{200}2$

So firstly we will connect two cells in parallel . Then the net Voltage will be equal to (1.5 V + 1.5 V ) = 3 Volts .

Again we will similarly connect two cells in parallel . Then the net Voltage will be equal to (1.5 V + 1.5 V ) = 3 Volts .

Now we know that when we connect identical cells in parallel then the net Voltage is equal to the each identical cell's voltage .

So finally we will connect these two series combination in parallel. Hence the net Voltage is equal to 3V .

$\boxed{\pink{\frak{ Hence \ we \ got \ 3\ V \ from \ 4 \ cells . }}}$
