Question

Calculate the combined
resistances of three
resistances 4 ,6 and
8 connected in series.​

Answer 1

Answer:

Maximum = 18 ohm

Minimum= 1.85 ohm

Explanation:

Maximum resistance is obtained when they are connected in series and minimum is obtained when they are connected in parallel circuit combination.

Since, in series combination

R(equivalent)= (4+6+8)ohm

=18 ohm

Since, in parallel combination

1/R(equivalent)=(1/4)+(1/6)+(1/8)

therefore, R(equivalent)= 24/13

=1.85 ohm
