Series grouping of Resistance is considered one of the most asked concept.
16 Questions around this concept.
A cell of emf $
90 \mathrm{~V}
$ is connected across series combination of two resistors each of $
100 \Omega
$ resistance. A voltmeter of resistance $
400 \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 :
Series Grouping of resistance
In this case , Potential drop is different across each resistor and Current is the same
.
Equivalent Resistance
For n identical resistance:
