In the circuit diagram, what does the line segment with two circles at the ends represent? an electrical conductor a source of electrical energy an electrical resistor a closed switch

That is a symbol for a closed switch meaning that current flows through the wire. If the line between the two circles wasn't connected to one of the circles, then it would be an open circuit in which current doesn't flow through the wire.

closed switch

Explanation:

Closed switch is when current is allowed to flow freely without hindrance.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

c) up

hope this
