Question

a 9 ohm resistance is cuted in three equal parts and connectd in parallel. find he equivalent resistance of the combination

Answer 1

Answer:

1 ohm

Explanation:

total resistance =9 ohm

Therefore,resistance in each part of resistor

= 9/3

= 3 ohm

So, equivalent resistance in parallel

= 1/R

= 1/(R1) + 1/(R2) +1/(R3)

= 1/3 + 1/3 + 1/3

= 3/3

= 1 ohm
