What is the purpose of the resistor?
I was about to ask that exact thing what is the resistor for
Forward Voltage of green LED's is 1.4-2.6V, so some voltage needs to be broken down since the battery is 3V. Voltage exceeding 2.6V will burn the green LED's.
How many led can be used with 1 battery?without any resistance??
omly one
more than one... if the combined voltages of the LEDs do not exceed the 3 volt battery. Different colours use diff voltages. (two is the most)
Why do you need to twist the tails?
