Question

1. Two different R resistors in parallel always have the same ____________; two resistors in series always have the same ______________.

A) voltage drop, voltage drop

B) voltage drop, current

C) current, current

D) current, voltage drop

2. The equivalent resistance of two or more resistors in series and parallel is best summarized by:

A) is always smaller than the largest R
B) is always less than the smallest R
C) larger than the largest single R in series, less than the smallest single R in parallel
D) is always less than the largest R
E) larger than the smallest single R in series, less than the largest single R in parallel
F) larger than the largest single R in parallel, less than the smallest single R in series
G) is always larger than the largest R
H) larger than the smallest single R in parallel, less than the largest single R in series

I am pretty sure it's C, but I just want to make sure

3.

Most devices are connected in:

A) series, so one going out doesn't affect the others
B) series, since it reduces the equivalent resistance of the devices
C) parallel, so one going out doesn't affect the others
D) parallel, since it reduces the equivalent resistance of the devices

I am pretty sure this one is C as well, but again I would just like to make sure my thinking is correct. Thanks!

Explanation / Answer

1) B) voltage drop, current

2) C) larger than the largest single R in series, less than the smallest single R in parallel

3) C) parallel, so one going out doesn't affect the others.
