Question

a wire of resistance 1 ohm is divided into two halves and voth halves are connected in parallel the new resistance is :(1) 1 ohm (2) 2 ihm (3) 0.5 ohm (4) 0.25 ohm​

Answer 1

Hey mate ✌✌✌

Here is your answer

Answer:

Resistance = 1 ohm

for parallel ,

1/Rp = 1/R1 + 1/R2

R1 = 1 ohm

R2 = 1 ohm

1/Rp = 1/1+1/1

1/Rp = 2/1

Rp = 2

.: new resistance in parallel is 2 ohm .

option (2) 2 ohm .

Hope it helps you . :--)

Answer 2

Answer:

so,

it is divided in half then R will become 0.5

in parallel

1/R =1/0.5 +1/0.5

1/R = 20/5

1/R= 4

reciprocal it

R= 1/4

R= 0.25 ohm

jo dusre ne answer diya hai na wo totally wrong hai

and mera bilkul right hai

THE CORRECT ANSWER IS 0.25 OHM
