Question

2. If several resistors are connected in parallel, what do we know about the total resistance?

a. It is the sum of the individual resistors.
b. The total has a value lower than any of the individual resistors.
The total is greater than any of the original resistors.
C.

Answer 1

Hi there!

B. The total has a value lower than any of the individual resistors.

Based on the equation for resistors in parallel:

`(1)/(R_T) = (1)/(R_1) + (1)/(R_^2) }+ ...+(1)/(R_n)`

The total resistance is the reciprocal of the inverses of each resistance summed up.

Thus, for any resistance and amount of resistors in parallel, the total resistance will have a value lower than any of the individual resistors.
