Question

how the register of resistance 2 ohm 3 ohm and 6 ohm be connected so that the equivalent resistance becomes 4 Ohm

Answer 1

HEYA...

3 ohm and 6 ohm should be in parallel ..so that they give equivalent of 2 ohm

then that would be in series with 2 ohm to get equivalent of 4 ohm.


Mathematically

1/3 + 1/6 = 2. ( Parallel )


now remaining 2 ohm in series with 2 ohm that we got

–» 2 + 2 = 4 ohm

Answer 2

heya mate here is ur anss
=====================
6ohm resistor and
3ohm resistor give equivalent resistance of 2 ohm and next u need to connect the initial 2 ohm resistor with the parallel combination of 6 and 3 ohm in series should be
connected in parallel combination , with 2 ohm and hence u connected it in series then resistance of whole circuit = r1+r2= 2 +2=4
