1) If a current flows through water and a LED connected in series, the LED will

not light up

vibrate and create a sound

light up

squeal

Clear selection

2) The better a solution conducts electricity, the....

2 points

more brightly a LED will glow

more loudly a 555 timer will squeal

higher the pitch of a 555 timer

the more brightly a LED will glow and the higher the pitch of a 555 timer

3) Salt water compared to tap water...

2 points

salt water conducts worse

if tap water has resistance 300 k Ohms, salt water has resistance 800 k Ohms

if tap water has resistance 800 k Ohms, salt water has resistance 300 k Ohms

salt water makes the LED go out
