Question 20: NCERT Solutions for 12th Class Physics: Chapter 3-Current Electricity
(a) Given n resistors each of resistance R, how will you combine them to get the
- minimum effective resistance? What is the ratio of the maximum to minimum resistance?
(b) Given the resistances of 1 Ω, 2Ω, 3Ω, how will be combine them to get an equivalent resistance of
- (11/3) Ω
- (11/5) Ω,
- 6 Ω,
- (6/11) Ω?
(c) Determine the equivalent resistance of network shown in figure.
(b) All possible combinations with resistances 1 Ω, 2 Ω and 3 Ω are
So, the combinations for the desired results can be selected.
