Question

You arc given 10 resistor 20 cach.
a.What is the value of maximum of maximum and minimum resistance that can be obtained by combining them?

Answer 1

Answer:

200 ohms and 2 ohms

Explanation:

Series connection :

R in series =R1+R2+R3+.............R10

= 10(20)

= 200 ohms (max)

parallel connection :

1/R in parallel = 1/R1 + 1/R2+.....1/R10

= 10(1/20)

= 1/2

R I parallel = 2 ohms (min)
