Question

how will you attach a 6 ohm of 3 different registers so that the value of equivalent resistance will be :
(a) 2ohm
(b) 4 ohm​

Answer 1

Answer:

for 2 ohm connect them in parallel nd for 4ohm connect them in first two in series then one in parallel

Explanation:

1/rp=1/6+1/6+1/6

=3/6=1/2

rp=2ohm

rs=6+6=12ohm

1/rp=1/rs+1/6

=1/12+1/6

=1+2/12

=3/12=1/4

rp=4ohm
