Question

Calculate the resistance between X and Y

Answer 1

1 ohm and 2 ohm are in series

Rs=3 ohm

3 ohm and 1.5 ohm are in parallel

Rp=1.5×3/4.5=4.5/4.5=1

1 ohm , 3 ohm and 3 ohm in series

Rs=7 ohm

Answer 2

Answer:

Explanation:

HERE THE 1 OHM BETWEEN RP AND 2 OHM BETWEEN RQ ARE IN SERIES .

R₁NET = 1+2 = 3 OHMS.

THIS 3 OHM AND THE 1.5 OHM BETWEEN PQ ARE IN PARALLE.

R₂NET = 3*1.5/(3+1.5)

           = 3*1.5/4.5

           = 1 OHMS.

THIS 1 OHM , 3 OHM BETWEEN XP AND 3 OHM BETWEEN QY ARE IN SERIES.

R NET = 3+1+3

          = 7 OHMS.

HOPE THIS HELPS.
