Edited By admin | Updated on Sep 18, 2023 18:34 AM | #JEE Main

## Quick Facts

• Series grouping of Resistance is considered one of the most asked concept.

• 16 Questions around this concept.

## Solve by difficulty

A cell of emf $90\mathrm{V}$ is connected across series combination of two resistors each of $100\mathrm{\Omega }$ resistance. A voltmeter of resistance $400\mathrm{\Omega }$ is used to measure the potential difference across each resistor. The reading of the voltmeter will be:

Given below are two statements :
Statement I: The equivalent resistance of resistors in a series combination is smaller than the least resistance used in the combination.
Statement II: The resistivity of the material is independent of temperature.

In the light of the above statements, choose the correct answer from the options given below :

## Concepts Covered - 1

Series grouping of Resistance
1. Series Grouping of resistance

In this case , Potential drop is different across each resistor and Current is the same

.

$R_{eq}=R_{1}+R_{2}+R_{3}+\cdots+R_{n}$

$R_{eq}=$Equivalent Resistance

For n identical resistance: $R_{eq}=nR$

$V'=\frac{V}{n}$
