What are the possible values of resistances which one can obtain by using resistors of values 2‎Ω, 3‎Ω and 6‎Ω? Justify your answer.

(d) 1 Ω is the maximum resistance

Minimum resistance is observed when they are connected in parallel (you can take it as a thumb rule that the resistance of a group of resistors connected in parallel will...

Solution: Every composite number can be expressed (factorised) as a product of primes and this factorisation is unique, apart from the order in which the prime factors occur. Yes.  Justification: HCF...

Regular exercise always promotes healthy aging process. Getting older is a regular cycle of life. Regular exercise delays the changes which occur due to ageing. The role of regular exercise...

396 = 1 × 231 + 165 231 = 1 × 165 + 66 165 = 2 × 66 + 33 66 = 2 × 33 + 0 ∴ The HCF of 231, 396...
