Question

three resistors of resistances 2Ω each are connected in parallel. Find the equivalent resistance of the combination

Answer 1

Answer:

3/2 ohm = 2/3 ohm

Explanation:

Parallel connection

1/R= (1/2+1/2+1/2)

= (1+1+1/2)

= 3/2 ohm

R= 2/3 ohm or 0.6ohm

Answer 2

Answer:

The correct answer for this question will be 2/3 ohm.

Explanation:

Ohm's law states that the current across a conductor between two points is directly proportional to the  applied voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I=V/R, where I is the current through the conductor, V is the voltage measured across the conductor and R is the resistance of the conductor.

The applied resistance is in parrel connection

The formula will be ,

1/R =  1/R1+ 1/R2 + 1/R3 .......... and so on

$1/R= (1/2+1/2+1/2)= (1+1+1/2)= 3/2 ohmR= 2/3 ohm or 0.6ohm$

Therefore the correct answer for this question will be 2/3 ohm.
