Question

Several resistors are connected in parallel. Which of the following statements are true of the corresponding equivalent resistance? (Select all that apply.)

It is greater than the resistance of any of the individual resistors.

It is equal to the reciprocal of the sum of the inverses of the resistances of all the resistors.

It is dependent on the voltage applied across the series.

It is less than the resistance of any of the individual resistors.

It is equal to the sum of the resistances of all the resistors in the series.

Explanation / Answer

Here ,

the voltage across the resistors will be same

I = V/R

for the equivalent resistance

Req = R1 * R2/(R1 + R2)

1/Req =1/R1 + 1/R2

the correct options are

It is equal to the reciprocal of the sum of the inverses of the resistances of all the resistors.

It is less than the resistance of any of the individual resistors.
