b) 6ohm
c) May be 10 ohm
d) Must be 10 ohm

please someone tell the answer with explanation..
don't answer if u don't know...
the answer is not 10 by the way please give the right answer with explanation.​

Answer 1

$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

( a ) 4 ohm .

Answer 2

Answer:

Effective resistance = 4 Ohm

Explanation:

• In the given diagram, the current is flowing from A to B.
• But after passing through 4 Ω resistance, that is after passing from AX we can observe a short circuit.
• In the short circuit, the current directly flows from point Y to point Z without passing through WY.

So, the effective resistance would be equal to the first resistance.

∴ The effective resistance = 4 Ω

Know more :-

If there was no short circuit in between, then the effective resistance would have been 4 Ω + 6 Ω which is 10 Ω.

Effective resistance is the sum of all Resistances in the circuit.
