Question

3 resistors having Equal resistance when combined in series having equivalent resistance 45ohm. The equivalent resistance when connected parallel....(a) 15 ohm
(B) 5 ohm
(C)30 ohm
(D) 90 ohm

Answer 1

Answer:

As per the data,

R

s

= 3R = 90 ohm

∴ R = 30 ohm

R

p

1

=

R

3

∴

R

p

1

=

30

3

∴ R

p

= 5ohm

Answer 2
