Question

10 resistors of 2 ohm each are given.
a) Calculate the highest resistance that you can get using
all of them? b)Calculate the lowest resistance that you can get using
all of them?

Answer 1

Answer:

do and understand

Explanation:

Given : R=2Ω n=10

Minimum resistance is obtained when all the 10 resistors are connect in parallel.

Minimum resistance R

min

=

n

R

=

10

2

=0.2Ω

Maximum resistance is obtained when all the 10 resistors are connect in series.

Maximum resistance R

max

=nR=10×2=20Ω

Ratio of maximum to minimum resistance

R

min

R

max

=

0.2
