Question

Five resistances each of 2 ohm are connected in parallel. What is the total residtance ?​

Answer 1

Answer:

one ohm

Explanation:

as it will be

1/R=1/r1+1/r2+1/r3+1/r4+1/r5

i.e. 1/R =1+1+1+1+1/5

R=1

Answer 2

Answer:

2.5 ohm

Explanation:

resistance parallel = 1/2+1/2+1/2+1/2+1/2

as there are 5 resistors

now, it will be 5/2 = 2.5 ohm
