Question

Calculate the (i) highest and (ii) lowest resistance that can be obtained by combination of three resistors of resistances 20 ohm, 30 ohm and 60 ohm​

Answer 1

Answer:

(Bruh why you guys asking in math go ask in Physics)

Step-by-step explanation:

(i)Highest resistance can be obtained by series connection of all the resistors

i.e 20ohm + 30 ohm + 60 ohm = 110 ohm

(ii)Lowest resistance can be obtained by parallel combination of all the resistors

i.e 1/20 + 1/30 + 1/60 = 1/10

resistance = 10ohm
