Series grouping of Resistance is considered one of the most asked concept.
16 Questions around this concept.
In the given circuit, an ideal voltmeter connected across the $10 \Omega$ resistance reads 2 V . The internal resistance r (in $\Omega$ ), of each cell is :
Series Grouping of resistance
In this case , Potential drop is different across each resistor and Current is the same
.
$
R_{e q}=R_1+R_2+R_3+\cdots+R_n
$
$R_{e q}=$ Equivalent Resistance
For n identical resistance: $R_{e q}=n R$
$
V^{\prime}=\frac{V}{n}
