2 resistors R1=2ohm and R2=8ohm are connected parallel to a cell of voltage V and internal resistance 'r'.What happens to the voltages across R1and R2,if R1 is decreased??

Solution

Hi,

In a parallel circuit, the voltage across each of the components is same. It does not depend on the value of resistance of the component. Therefore, voltage across R₁ and R₂will be equal to the voltage of cell i.e. V.
