Question

find the effective resistance
r1=3ohm
r2=3ohm
r3=3ohm​

answer the question soon

Answer 1

If we take any two of the resistances,they'll be in series.

So, R1 + R2 = Rs

Rs = 3 + 3 = 6 ohm

Rs and bc are in parallel.

So, 1/R1 + 1/R2 = 1/Rp

1/6 + 1/3 = 1/Rp

》Rp = 1/2 ohm

HOPE IT HELPS YOU.

Answer 2

Answer:

1/R parallel= 1/3+1/3=2/3

R total= 3+ 3/2

= 9/2
