measuring current

which of the following shows how to correctly measure the current flow between the lightbulbs connected in series?

Explanation:

To measure current between two series-connected lightbulbs, an ammeter must be connected in series within that specific segment of the circuit, breaking the connection between the bulbs and inserting the ammeter into the gap so all current flows through it.

• The first option places the ammeter at the end of the circuit, not between the bulbs.
• The second option places the ammeter outside the series path of the bulbs.
• The third option correctly inserts the ammeter directly between the two lightbulbs, in series with them, so it measures the current flowing between them.
