    did you say which size resistor to use and why? people what you need to do to calculate the resistor size to use is the use the equation R=V / I. R=resistance, V=volts and I=current. you will find a current rating from the manufacturer of the LED. let’s say it’s 1mA (or 0.001A). therefore R=9 / 0.001 = 9000 ohms

    Yes you can, it’s good practice to use a bread board aswell.

  4. because electrons …
    because electrons are negatively charged and the energy/electricity is just the flow of electrons

  5. dont the electrons/ …
    dont the electrons/charges flow from the negative terminal to the positive terminal?

    can u use a breadboard in stead off allagator clips? if u no kinda wat i mean

    you’re hot and smart. I’d love to know as half as much as you know. Have you graduated yet? (collage) if yes, what was your degree on?
