1. When I connected points C and D, the green LED light turned on, while red light didn't turn on. Why doesn't the red LED light up ? 2. When I connected the jumper wire between points B and C, none of these LED lights turned on. What does this tell you about the voltage across each parallel branch? Why one LED easily lights, while two in series do not light ? 3.If the battery source provides 3 V, is it possible to power 10 LEDs in parallel?Explanation / Answer
1)
When you connected points C and D, the green LED light turned on,
It is because of closed circuit.
red LED is in open circuit.
2)
a LED is a diode.
diodes should connect in parallel only.
3)
yes,
voltage for each LED is 3/10=0.3 v.
