Question

A man has five resistors each of value 0.2 ohms . Find the maximum resistance obtain by connecting them

Answer 1

Answer:

Series - (1ohm )

Parallel - (0.04ohm)

Explanation:

In series -: R1 +R2+ R3+ R4 +R5=R

0.2+0.2+0.2+0.2+0.2=(1ohm)

In parallel - : 1/R = 1/R1+ 1/R2 + 1/R3 +1/ R4+ 1/R5

1/R= 1/0.2+1/0.2+1/0.2+1/0.2+1/0.2

R= (0.04 ohm)

Answer 2

Explanation:

if it is in series then r1+r2+r3+r4+r5=0.2+0.2+0.2+0.2+0.2=1ohm
