Answers
Given :
Four resistors each of resistance 1/2 Ω i.e.,
- R₁ = 1/2 ohms
- R₂ = 1/2 ohms
- R₃ = 1/2 ohms
- R₄ = 1/2 ohms
To find :
The maximum resistance of the resistors connection.
Solution :
The maximum resistance can be obtained when it is connected in series.
» The combined resistance of any number of resistance connected in series is equal to the sum of the individual resistances. i.e.,
By substituting the values,
Thus, the maximum resistance obtained is 2 ohms.
Hence, option (a) 2 ohms is correct.
Remember !
SI unit of resistance is ohms.
Given :-
Four resistors each of resentence 1/2 Ω i.e.,
- = 1/2 ohms
- = 1/2 ohms
- = 1/2 ohms
- = 1/2 ohms
