Question

plz solve the (d) question:)​

Answer 1

Total resistance: 2 Firstly both main lines are in pararrel circuit.

in the upper circuit, both 1 ohm resistances are in series circuit, the 2 ohm resistances are in series circuit.

Now, the 2 ohm resistances and the 4 ohm resistance are in parallel circuit,

Therefore, 1/Reqv. = 1/4 + (1/2+2)

= 1/4 + 1/4

= 2/4

Reqv. = 2 ohm

Now, for the whole upper circuit,

Reqv. = 1+2+1= 4 ohm

Now, for the whole circuit,

1/Reqv. = 1/4 + 1/4

= 2/4

Reqv. = 2 ohm
