Question

Jasmine makes a note card about series circuits. She records the points shown.

A 2 column table with 1 row. The column on the left is labeled advantages with entries (1) they are simple to design and build. The second column is labeled disadvantages with entries (2) each source of current used adds more current to the circuit, (3) the more bulbs are added the dimmer the bulbs are, (4) if one bulb goes out they all go out.

Which change will correct the error on her note card?

switching the headings on the columns
adding the title Parallel Circuits
moving point (2) into the Advantages column
moving point (4) into the Advantages column

Answer 1

Moving point (2) into the Advantages column.

Reason: adding sources (batteries) in series increases the total voltage (and thus the circuit current), so that is an advantage of a series connection. The other listed items (more bulbs dimmer, and one out → all out) are true disadvantages.
